Faviana S10659 Long Mermaid Sweetheart Open-Back Stretch Jersey Gown

Faviana S10659 earns its place in a very crowded category of mermaid prom gowns by doing something most of them avoid: removing almost everything. No beading, no sequin, no lace overlay, no embellishment of any kind. Most mermaid gowns at this price point use surface decoration to create drama. This one creates it entirely through cut and skin. The full open back — bare from shoulder blades to the lower waist — is the single loudest design element on the dress, and the only thing framing it are two thin spaghetti straps that cross at the shoulders. That restraint is what makes it hit harder than heavily decorated alternatives when you walk into a room. The silhouette itself is also precisely executed. The stretch jersey fabric is tight enough to trace the body cleanly through the bust, waist, and hips, but it has real give, so it moves when you move instead of fighting you. A lot of mermaid gowns in structured or layered fabrics look great in photos and feel restrictive the moment you try to climb stairs or take a full step. The jersey construction here avoids that problem — the flare at the knee gives you the mobility you need without the dress losing its shape. The sweetheart neckline adds one more layer of balance. It frames the chest cleanly and keeps the front structured while the back is completely open. The front-to-back contrast — covered and shaped at the front, dramatically bare at the back — is the whole point of the dress. If you are comparing this to a sequin mermaid gown or a lace-fitted gown, the question is really about what kind of impact you want. Heavy embellishment gets attention at close range and in photos. A perfectly cut open-back mermaid in a clean matte fabric gets attention the moment you turn around. Faviana S10659 is designed for that second kind of entrance. It is also worth noting that the sage green colorway photographs differently depending on light. Under warm indoor event lighting it leans warm and soft. Under cooler or brighter light it reads as crisper and more assertive. If you want the dress to look dramatic in photos, pay attention to the lighting at your venue — this color rewards it.

Faviana S10659 is best suited to prom, formal dances, and evening events where a sleek, body-close silhouette with significant back exposure is appropriate. It is a strong prom gown choice — the mermaid cut, the open back, and the clean stretch jersey all align with what prom calls for. For a formal dance where you want to stand out without going over-the-top with embellishment, this dress delivers. Beyond prom, it works for formal evening occasions where guests are expected to dress up and where the environment is a party or celebration rather than a ceremony. Think post-prom, a formal dinner event, or a high-end evening occasion where a fitted gown is the right call. The fact that it has no beading or sequin means it does not read as a purely themed or heavily decorated gown — it is versatile within the formal evening category. There are events this dress is genuinely not right for, and it is worth being direct about them. Because the back is fully open — bare all the way from the shoulder blades to the lower waist — it does not work for events that call for covered or modest styling. Wedding guest occasions typically exclude full open-back gowns for that reason. Military balls also require covered backs by convention. Any event with a dress code that leans conservative is not a match. If you are shopping this dress for a specific event and you are not sure whether the back exposure fits the occasion, the safest approach is to check the dress code language for your event first. When the code says formal or black tie without additional modesty requirements, this gown fits. When the event has uniform protocols, traditional ceremony elements, or a conservative guest list, size the exposure against those expectations before ordering. For prom specifically, Faviana S10659 is a confident, on-target choice. The silhouette, the color, and the drama of the open back are all built for that kind of occasion.

Faviana S10659 does not have a traditional back closure. Because the back is fully open — bare from shoulder blades to the lower waist — there is no zipper, lace-up, or corset panel across the back to tighten or loosen. The fit comes entirely from the stretch jersey fabric and the cut of the dress itself. The two thin spaghetti straps cross at the back and connect at the shoulders. These are not adjustable in length on a standard construction, so the support and positioning of the straps depend on the garment's sizing rather than a buckle or slider. If the straps feel too loose or the front pulls, a tailor can shorten them by taking in the connection points at the shoulder or back. Because there is no adjustable closure, getting your size right before ordering is more important here than it would be on a gown with a lace-up back. Measure your bust, waist, and hips against the Faviana size chart, and if you are between sizes, size up — the jersey does have give, but going too small in a mermaid silhouette creates visible pulling at the hips. Sizing up and having the waist nipped in by a tailor is a much easier fix than trying to let out a dress that is too tight. Alterations on stretch jersey are straightforward for an experienced tailor.

Faviana S10659 can work as a group gown, but there are a few practical things to think through before committing the whole court to it. The open back is the biggest consideration — not every person in a group is equally comfortable with full back exposure, and it is worth having that conversation before the order goes in. If the group is on board with the silhouette, the sage green colorway is a strong choice for a coordinated look. It is a distinctive enough color that it reads as intentional when multiple people wear it together, without being as saturated or aggressive as a deeper green. It photographs well as a group and works across different skin tones. For groups where some members want more back coverage, Faviana's broader collection includes fitted mermaid styles with different back constructions. Mixing styles within the same color family can work well as a coordination strategy — same color, different silhouettes — rather than requiring everyone to wear the identical dress. If you want help identifying complementary Faviana styles for a court or group, the Marlas team can pull options for you based on your color and silhouette requirements. In terms of sizing consistency, the stretch jersey fabric means fit will look slightly different from person to person depending on body shape, which is normal for a body-close mermaid. Plan for individual fittings and alterations rather than assuming the same size fits every member of the group the same way.

Faviana S10659 runs true to Faviana's standard sizing in most cases. For a mermaid gown in stretch jersey, the critical measurements are bust, waist, and hip — all three need to fall within the same size column on the Faviana size chart. The hip measurement is often the deciding factor on a body-close mermaid, because that is the tightest point of the silhouette before the flare begins. Measure your bust at the fullest point, your waist at the natural waist (not the low waist), and your hips at the fullest point — typically 7 to 9 inches below your natural waist. Compare all three to the Faviana size chart and size to whichever measurement falls highest on the chart. If your hip measurement puts you in a size 6 but your waist puts you in a size 4, order the 6 and have the waist taken in. If you are between sizes, always size up on a fitted mermaid. Taking in a seam is simpler and less expensive than letting one out, and many stretch jersey gowns do not have enough seam allowance to let out safely. Plan at least two to three fittings with your tailor: one to assess overall fit after the dress arrives, one after alterations, and a final check in your shoes.

The open back on Faviana S10659 rules out standard bra styles entirely — the back is exposed all the way to the lower waist, so any traditional bra will show. The stretch jersey fabric has enough structure at the chest to provide light support on its own for most bust sizes, but for additional support, the options are adhesive bras, silicone cups, or low-back bra converters that sit low enough to stay hidden. The sweetheart neckline works best with a low-profile or strapless adhesive solution. Stick-on silicone cups give a natural shape without adding visible hardware under the fabric. For larger bust sizes where more support is needed, a low-back adhesive bra with a more substantial cup can work, but test the adhesive on a small area of the jersey fabric before wearing it for a full evening — stretch fabrics vary in how well adhesives hold and whether the backing leaves marks. For shapewear, the mermaid silhouette means anything worn under the skirt will be visible. If you want to smooth the hip line, a low-waist brief-style shaper that ends at the hip — not a full brief that hits higher — sits cleanly under the flare without creating a visible line at the hip.

Marlas Fashions accepts returns for store credit, exchange, or refund. Refunds are issued less a 30% restocking fee, which reflects the cost of inspection and restocking a formal gown. Store credit never expires, so if Faviana S10659 is not the right fit or the right dress, the credit carries over to your next purchase with no deadline. To be eligible for a return, the dress must be in its original unworn condition — no alterations, no damage, no evidence of wear. Once a gown has been altered or worn, it is no longer returnable. This is standard across formal wear retailers because an altered gown cannot be restocked. If you receive the dress and something is wrong — a defect, a damage issue, or a significant discrepancy from what was described — contact the Marlas team immediately with photos. Issues flagged within the return window are handled directly and quickly. Every dress at Marlas is inspected before it ships, but if something slips through, the team will take care of it. For exchanges, if you need a different size, contact the team as soon as the dress arrives and you have tried it on. Moving quickly on a size exchange gives you the best chance of the correct size being in stock in time for your event.
