Frequently Asked Questions

How does the back closure on the Portia and Scarlett PS27143 work, and can I adjust the fit at the back?

The Portia and Scarlett PS27143 closes at the back with a halter tie at the neck — there is no zipper, corset lacing, or hook-and-eye running down the back. The halter tie allows a small degree of adjustment at the neckline: you can tie it tighter or looser to sit higher or lower at the back of the neck. Because the entire back is open and bare from that tie point all the way down to the waistband, there is no back panel to let out or take in. This is an important fit point to understand before you order. All of your fit decisions for this dress get made at the bodice front — the bust cups and the structured waist panels. Portia and Scarlett sizes this style in standard formal-wear measurements, so use your full bust, natural waist, and high hip measurements against the brand's size chart. If your measurements put you between two sizes, size up. A local bridal or formal-wear tailor can take in the waist seam at the front of the bodice and adjust the side-waist cutout panels to sit correctly against your body. That alteration is straightforward and does not touch the back construction at all. The cutout panels on either side of the waist are a fixed design element — they are not adjustable in the way a corset back would be. If you have a narrower waist relative to your bust, the structured bodice will hold its shape well. If your waist is closer to your bust measurement, the cutouts will sit flush and clean. Where some customers run into a fit issue is if the waist measurement is significantly larger than the bodice is cut for — in that case, sizing up to fit the waist and having the bust cups adjusted by a tailor is the cleaner path. The skirt is a full a-line with no closure — it simply falls from the waistband. There is nothing to adjust at the hem except a standard length alteration if the floor-length hits too long for your height. Allow several weeks before your event for alterations, especially during prom season when tailors book up quickly. Order as early as you can — PS27143 typically ships within seven to twelve business days from our Los Angeles or New York warehouse, so factor that into your timeline.

What occasions and events is the Portia and Scarlett PS27143 best suited for, and are there any events where it might not be appropriate?

Portia and Scarlett PS27143 is built for high-energy formal occasions where a bold, open-back look fits the dress code. The primary occasions this dress is designed for are prom, formal dances, evening events, and galas. The deep halter v-neckline, the fully bare back, and the floor-length sequin lace skirt all point to an event where dressing up all the way is expected and celebrated. For prom, this dress hits every mark. The full a-line skirt photographs beautifully under event lighting, the sequin lace picks up color in flash photography, and the open-back design gives it a distinctive look that stands out on a crowded dance floor without being overdressed. It works equally well at formal dances, winter balls, and military balls — anywhere the dress code calls for a full-length gown and a statement silhouette. For evening events and galas, PS27143 reads as polished and intentional. The structured bodice and tiered skirt keep it from sliding into costume territory, and the minimalism of the silhouette — no sleeves, no accessories built into the design — means it pairs easily with whatever jewelry and shoes you choose. As a wedding guest, the open back and midriff cutouts mean it suits evening or black-tie receptions best, where a more fashion-forward look is welcome. The open back and exposed midriff cutouts make it too revealing for a wedding setting, where the guest dress code generally calls for something more covered. It also is not the right call for religious ceremonies, confirmation events, or conservative formal settings where covered shoulders and backs are expected. If you are shopping this dress for a theme or setting you are unsure about — a black-tie dinner, a debutante event, or a formal charity gala with a specific dress code — the safest move is to check the event's guidelines first. The dress is genuinely versatile within its category, but the open back is a real design element that you need to plan around, not a subtle detail.

Does the Portia and Scarlett PS27143 run true to size, and how do I measure correctly for this style?

Portia and Scarlett PS27143 runs in standard formal-wear sizing. Most customers find it runs true to size when measured correctly — the key is using your full bust, natural waist, and high hip, not your clothing size from another brand. For this specific dress, the waist and bust measurements are the most critical. The bodice is structured, the cutout side panels are fixed in position, and the halter v-neckline sits close to the body. There is no corset lacing or back zipper to fine-tune the fit after the fact. If your measurements put you between sizes, size up — it is easier for a tailor to take the waist in than to let it out. If you are unsure which size to order, or if your measurements fall at the very edge of a size range, our team is happy to help you compare against the size chart before you place your order. Text or WhatsApp us at any time and we will walk through the measurements with you. Call or text our Toronto boutique at 416-536-2956 and our stylists will help you find your perfect dress.

What undergarments work best with the Portia and Scarlett PS27143, and does it have built-in support?

The bodice of Portia and Scarlett PS27143 has structured cups built into the front bodice, which provides a reasonable degree of bust support on its own. Most customers with a B or C cup find the built-in support sufficient for a full evening. Customers with a fuller bust may want additional support, but the open back and halter tie closure rule out a traditional bra entirely — there is no back panel to hide straps against. The most practical solutions for this dress are adhesive bra cups or a low-back strapless option worn under the bodice. Silicone adhesive cups in a shade close to your skin tone work well and stay invisible under the deep v-neckline. Avoid anything with a visible band across the back — the back is completely bare and any strap will show. For the skirt, the full a-line silhouette means you can wear a seamless brief or shorts underneath without any visibility issue. Shapewear that ends at the waist rather than the hips works best to avoid a visible line under the structured waistband.

Can the Portia and Scarlett PS27143 be hemmed or altered for my height?

Yes, PS27143 can be hemmed. The skirt is a full a-line in tiered sequin lace, which means hemming does require a tailor experienced with layered lace — it is not a single-fabric hem you can do at home. The tiered construction means each layer needs to be addressed individually to keep the bands landing at the right visual proportions. For standard height alterations — shortening by one to three inches for a petite frame — most formal-wear tailors handle this routinely. For a larger adjustment, ask the tailor to confirm they are comfortable working with sequin lace before committing. A bad hem on a tiered lace skirt is difficult to undo. At the bodice, the halter neckline can be adjusted slightly by retying, but structural alterations to the cutout panels or waistband should only be done by someone with experience in formal wear construction. The rest of the dress — the open back, the satin bow, the cup construction — is fixed and not typically altered. Build in at least two to three weeks before your event for alterations. During prom season, tailors in most cities book up fast, so do not leave this until the last week.

How does the Blue colorway look in person compared to photos, and what should I know about the Pink colorway before ordering?

The Blue colorway in PS27143 photographs very consistently with how it looks in person. It is a rich, saturated blue — not a pale powder blue and not a dark navy — that holds its color well under both natural light and event lighting. The sequin and glitter finish on the lace adds dimension to the color rather than washing it out, so what you see in the product images is a reliable representation. The Pink colorway is currently listed but not yet photographed on our site. We do not have studio images to share for Pink at this time. If you are considering the Pink version, we strongly recommend reaching out to us before ordering — our team can describe the exact shade, confirm availability in your size, and if possible share any designer reference imagery we have on file. Ordering a color you have not seen photographed is a risk we want to help you avoid. For both colorways, keep in mind that screen calibration varies — if color accuracy matters to you, asking our team for a direct description is always the safest step before placing your order.
