From the seamstresses at Lan’s Lapels — serving Wilmington, North Andover, Andover, Concord, and Lincoln.

Walk into any prom shop this April and you’ll see the same scene playing out: a teenager standing on a fitting platform, a parent holding up a phone for “the photo,” and a beautiful dress that’s about an inch too long, a half-inch too tight, or sitting just slightly off the shoulders. The dress isn’t wrong. It just isn’t finished.

That last mile — turning a dress off the rack into one that looks like it was made for the person wearing it — is what we do at Lan’s Lapels. Our master seamstresses have more than 40 years of experience between them, and during prom and wedding season our fitting rooms in Wilmington, North Andover, Andover, Concord, and Lincoln are where dresses come to be finished.

This year’s trends are giving us a lot to work with. According to TODAY’s 2026 prom preview and the season’s lookbooks from Faviana and Sherri Hill, corset bodices are everywhere, sparkle is back (more “glow,” less “costume”), and bold colors — magenta, sapphire, emerald, even tangerine — are out-shouting last year’s pastels. Tiered ruffles are dramatic again, and Regencycore bows and backless silhouettes are having a moment.

All of which is to say: 2026 dresses have a lot of structure. Structure is gorgeous. Structure also needs to fit perfectly, or it shows.

Here are three things our team wants every prom-goer (and every parent footing the bill) to know before the big night.

1. Five things to look for in a great alteration

A good alteration doesn’t change the dress — it disappears into it. When you’re choosing who works on your gown, look for:

Even hems. The hem should hit the same point all the way around when you’re standing naturally. Walk a few steps in your actual shoes during the fitting; if it’s pooling or bouncing, it isn’t done.
Clean bodice lines. Especially with this year’s corset trend, you want zero gaping at the top edge and no boning shifting under the fabric.
A real bustle. If your dress has any kind of train, ask to see how it will be pinned up for dancing. There should be a plan, not a “we’ll figure it out.”
Matched thread, hidden stitches. On the inside and the outside. If you can spot the stitching from across the room, ask why.
A final press. A finished alteration includes steaming. A dress that’s been pinned, sewn, and hung up without a press will look like exactly that.

2. The prom-dress fitting timeline (start now if you haven’t)

Here’s the calendar we run on at Lan’s Lapels:

4–8 weeks out: First fitting. We mark the hem, take in or let out the bodice, and plan straps or a bustle. Bring the shoes. We can’t say it enough — bring the shoes.
2–3 weeks out: Second fitting. Try everything together: dress, shoes, undergarments, jewelry. This is when small things get fixed.
3–5 days out: Pickup, pressing, and a final try-on. Leave room in case anything changed (and it does — proms famously fall right after a growth spurt or a stressful exam week).

If your prom is in May or early June and you haven’t started, today is the day to call.

3. How to look good in prom photos (a tailor’s secret)

Posture and fit beat filters every time. Three small things our seamstresses tell every client:

Stand on the balls of your feet, not your heels. It elongates the leg line in photos. This is exactly why we fit you in your shoes — we’re tailoring for how you’ll actually stand.
Drop the shoulders, lift the chest. Most “awkward photo” moments are tense shoulders, not a bad dress.
Let the dress move. Walk into the photo, don’t pose into it. Tiered ruffles, satin skirts, and beaded hems all look better with a half-step of motion.

A note from our team

Our master seamstresses have stitched, hemmed, and bustled their way through more than four decades of proms, weddings, and “I-need-this-by-Friday” emergencies. We’ve seen every trend come around twice. Most of all, we’ve watched a lot of people walk out of the fitting room standing a little taller — which is honestly the whole point.

If you have a prom dress hanging in your closet right now and you haven’t booked a fitting yet, call your nearest Lan’s Lapels location in Wilmington, North Andover, or Concord. Bring the shoes.

Lan’s Lapels is a family-run tailoring shop serving the Merrimack Valley and MetroWest with five neighborhood locations. Walk-ins welcome; appointments recommended during prom season.
