Frequently Asked Questions

What size should I order in Faviana 9570, and how does the mermaid silhouette affect the fit?

Faviana 9570 is sized using Faviana's standard plus size measurement chart, and the single most important step before ordering is taking three measurements: full bust, natural waist, and fullest part of the hips. Faviana's size chart uses all three together, so having only one or two can lead to an incorrect recommendation — write all three down before you open the chart. The mermaid silhouette of Faviana 9570 means the fit is form-fitting through the bust, waist, and hips — not just through the bodice. The jersey-based fabric has natural stretch, which gives the silhouette some recovery, but the gown is designed to sit close to the body from the shoulder to the knee. If your measurements place you between two sizes, we recommend sizing up. In a mermaid, a size too small restricts stride and makes the flare work against you rather than with you; a size larger can be taken in by a local tailor far more easily than adding fabric to a too-small gown. Pay particular attention to the hip measurement in Faviana 9570. Because the silhouette is fitted through the hips and only releases below the knee, the hip is often the deciding measurement — especially if your waist-to-hip ratio is pronounced. Do not size to the waist measurement alone. The straps are slim and fixed, and the crisscross open back means there is no conventional zipper running the full length of the dress. The open-back construction shapes the back through the strap placement rather than a boning structure, so the bodice relies on the jersey's compression and the strap tension together. If you are between sizes and carry more of your volume through the back and shoulders, sizing up and having the straps adjusted is the more comfortable route. If you would like a guided recommendation — tell us your bust, waist, and hip measurements and we'll match you to the right size from the Faviana chart. Orders ship within 7–12 business days from our US or Canadian warehouses, with rush options available if your event is sooner. Alterations are almost always needed on a mermaid gown, so build that time into your timeline and budget from the beginning.

Which events is Faviana 9570 designed for, and how formal do those occasions need to be?

Faviana 9570 is designed for occasions where a dramatic entrance matters — and where the room is large enough for a sweep train to move freely. The three strongest contexts for this gown are prom, formal evening events, and galas. At prom, Faviana 9570 performs particularly well. The mermaid silhouette is one of the most consistently photographed shapes on a prom floor because the fitted line through the hips creates a defined figure and the flared hem photographs with motion even in still shots. The asymmetric sequin floral appliqué trail adds a column of shifting light down the side seam that reads from across a grand ballroom. The open back and crisscross strap detail reward every rear-facing photo. Dark Emerald and Black read especially well under venue lighting. For formal evening events — dinner galas, charity fundraisers, corporate award evenings — Faviana 9570 sits at the upper end of the formality spectrum. The sweep train, the open back, and the sequin-beaded appliqués together signal a black-tie-adjacent level of dressing, so this gown works best when the event itself has an elevated dress code. It would feel out of proportion at a cocktail-code dinner. Faviana 9570 is not styled as a wedding guest gown. The combination of the open back, the fitted mermaid line, and the dramatic appliqué placement creates a look designed to stand out rather than complement, which places it outside the modesty and styling expectations for a wedding guest. Similarly, the gown's construction does not lend itself to mother-of-the-bride or quinceañera contexts. If you are unsure whether a specific event's dress code calls for this level of formality, consider the venue, the expected start time, and whether you will be dancing or seated for most of the evening. A sweep train on a formal dinner dance floor is entirely manageable; the same train at an outdoor event or on a cocktail-party floor may feel cumbersome. For events earlier in that formality spectrum, Faviana has other silhouettes better suited to those contexts.

What colorways does Faviana 9570 come in, and how do they photograph at an event?

Faviana 9570 is available in four colorways: Black, Dark Emerald, Ruby, and Sky Blue. All four are photographed on a plus size model on the Marlas Fashions product page, so you can evaluate the depth and saturation of each color against the same silhouette. Dark Emerald is the richest of the four — a deep jewel tone that reads as green-black in low light and opens to a saturated emerald under stage or venue lighting. It is an excellent choice for evening environments where the color needs to carry across a large room. Black is the most versatile for photography: the sequin floral appliqués catch light against the dark base in a way that makes the detail pop in both flash and ambient photography. Ruby is a warm, saturated red that reads confidently under venue lighting and photographs with strong contrast against most skin tones. Sky Blue sits at the lighter end of the palette — a cool, clear tone that can read icy or soft depending on the light temperature in the room. Under warm venue lighting, Sky Blue tends to warm slightly; under cool or daylight-balanced lighting, it maintains its clear blue quality. Text or WhatsApp us at +1 416-536-2956 or +1 213-868-3131 — we can confirm availability, share any additional photos we have on hand, and make sure you are ordering the right color for your event and skin tone.

How do the sequin floral appliqués on Faviana 9570 look and feel in person, and do they add significant weight to the gown?

The floral appliqués on Faviana 9570 are sequin-beaded motifs that cover the bodice and trail asymmetrically down the side seam toward the hem. In person, the effect is layered rather than flat — the individual floral shapes are dimensional, sitting slightly above the jersey base fabric, and the sequin detail on each petal catches light differently depending on the angle. The result is a gown that shifts subtly as you move, which is exactly where the styling focus — movement — pays off most. The appliqués are denser at the bodice and graduate to more spaced individual motifs as they travel toward the hem. This means the gown reads as moderately embellished when viewed at full length, without the all-over sequin weight of a fully beaded gown. The bodice carries the most embellishment, and the jersey skirt remains fluid and light below the knee, which supports comfortable movement throughout a long evening. In terms of physical weight, Faviana 9570 is lighter than a fully beaded ball gown. The jersey base is a stretch fabric, not a structured underlining, and the appliqués are surface-applied rather than woven into a heavy substrate. Most wearers find the weight manageable for a full evening, including dancing. The sweep train adds some trailing length to manage but not significant additional weight.

What is the train on Faviana 9570, and how do I manage it during an event?

Faviana 9570 has a sweep train — the shortest of the formal train lengths — which extends a short distance beyond the heel at the back hem. It is long enough to create a fluid, elongated silhouette in photographs and provide visible movement when you walk, but short enough that it does not require the same management as a cathedral or chapel train. For most prom and formal evening venues — ballrooms, event halls, hotel ballrooms — a sweep train moves naturally across the floor without significant intervention. On a dance floor, the train will trail behind you; when dancing, the movement of the skirt typically keeps it in motion rather than underfoot. Most wearers find they can dance freely without stopping to manage the train, particularly once the mermaid flare below the knee allows the legs to move. For moments when you need more control — navigating a crowded room, climbing stairs, or moving through tight spaces — you can carry the train by looping it over your wrist, or ask an escort to carry it briefly. Because Faviana 9570 does not have a bustle hook or loop built into the hem, you cannot permanently bustle the train, but for a sweep length, this is rarely necessary. On outdoor surfaces — grass, gravel, cobblestone — a sweep train will pick up debris. If your event has an outdoor component, plan to shake the hem before photographs. The jersey base fabric is relatively easy to spot-clean if needed.

What undergarments work best with the open-back, strapped design of Faviana 9570?

The crisscross open back and slim shoulder straps of Faviana 9570 eliminate most conventional bra options. The open back means the back band of a strapless bra would be visible, and the strap placement rules out most convertible styles. The most effective solution for most wearers is adhesive breast cups or a low-back adhesive bra, both of which provide lift and coverage without any hardware showing above the back waistline. The jersey-based bodice of Faviana 9570 has natural compression from the stretch fabric, which provides a base level of support on its own. Wearers with a smaller bust often find the jersey compression sufficient without additional undergarment support. Wearers who want or need additional lift will find adhesive cups the most compatible choice with this back construction. For shapewear, a high-waist brief or short works well under the mermaid skirt. Avoid any shapewear that extends above the hip line toward the back waist, as it could show above the back neckline depending on how the open back sits on your body. Footless, mid-thigh-length shaping shorts are the most practical option for a mermaid with a flared hem, as they do not interfere with the skirt's movement below the knee. For shoes, a pointed or slim-toe heel elongates the silhouette underneath the fitted hem. Because the mermaid flare is below the knee, you will need to be comfortable taking slightly shorter steps during the evening.

How long does delivery take for Faviana 9570, and is rush shipping available?

Faviana 9570 ships in 7–12 business days from order confirmation. Marlas Fashions ships from warehouses in Los Angeles and New York for US orders, and from our Toronto warehouse for Canadian customers — Canadian orders ship without duties or cross-border fees. International orders ship worldwide with full tracking provided at dispatch. If your event is approaching and the standard window does not give you enough time, rush shipping is available. Contact us before placing your order to confirm rush eligibility and any applicable expedited shipping cost — availability depends on current warehouse processing times at the moment of your order. Once your order ships, you will receive tracking information so you can monitor your delivery. We recommend building in a few additional days beyond the delivery window for any alterations your tailor may need — mermaid gowns in particular benefit from professional fitting, and local tailors typically need at least a week's notice for formal alterations work. For the most predictable result, allow at least three weeks between your order date and your event date. If you are ordering for an event with a hard deadline and you want to confirm the timeline before committing, our team can tell you whether your event date is comfortably within the standard window or whether rush options are recommended.

What is Marlas Fashions' return policy for Faviana 9570?

Marlas Fashions accepts returns on Faviana 9570 for store credit, an exchange, or a refund. Refunds are processed less a 30% restocking fee. Store credit never expires, so if you are undecided on an alternative style at the time of your return, you have no deadline pressure to use it. To be eligible for a return or exchange, the gown must be in its original, unworn condition with all tags intact. Gowns that have been altered, worn to an event, or laundered cannot be accepted back. If your order arrives with a manufacturing defect or a shipping discrepancy, contact us immediately — those situations are handled separately from standard return requests and resolved as a priority. Because Faviana 9570 is a mermaid gown with a fitted silhouette, we strongly encourage taking your measurements carefully before ordering and contacting us with any sizing questions before your purchase rather than after. Exchanges for a different size are processed subject to stock availability. If your preferred size is not in stock at the time of your exchange request, a store credit will be issued so you can apply it to an alternative style. For any questions about your specific return or exchange situation, reach out to us directly — we want the process to feel supportive and straightforward rather than complicated.
