The 374 guide to bridal shapewear

From backless dresses to sheer fabrics, we talk to stylist Aimée Croysdill on what to wear under your wedding dress

22 SEPTEMBER 2026

Shapewear has come a long way. No longer designed to pinch, squeeze or alter your body, the best modern shapewear is about creating a clean foundation, supporting the cut of a dress and - most importantly - being comfortable enough to wear all day.

 

For many brides, a wedding is the first occasion they’ll consider wearing it. For celebrity stylists, however, shapewear is one of the key foundations of nailing a red-carpet look. 

We asked Aimée Croysdill - the woman behind the epic wardrobes of Nicola Coughlan, Marisa Abela and Ellie Bamber - what she looks for in modern shapewear and how to find the right solution for your own wedding look. 

 

“Shapewear is such an integral part of finishing and perfecting a look, but for me it’s never about changing your body - it’s about changing the way the clothes sit on your body,” she says. 

“The right shapewear can make a dress look like it’s been poured onto the skin, rather than gathering or catching in places you don’t want it to. Sometimes it’s simply about creating that smooth layer underneath so a fabric can glide over the body rather than pucker, buckle or cling - you’re helping the clothes fall and behave exactly as they were intended to.”

 

That said, finding the right pieces isn’t always straightforward. Whether you’re looking for a smooth foundation beneath satin or are seeking a solution to a low back, the right underwear depends entirely on the fabric, cut and construction of your gown - and sometimes the best solution is barely anything at all. 

 

Here, we break down the bridal shapewear solutions worth knowing - and which dresses they work best with. 

Bridal shapewear: The 374 checklist

  • Take it to your dress fitting
  • Match underwear to your skin, not your dress
  • Check seams from the back as well as the front
  • Photograph your look in natural light
  • Wear-test tape and adhesive products beforehand
  • If your dress doesn't need it, don't wear it

Bodysuits

Best for: low-cut dresses, certain backless dresses and an all-in-one foundation

 

The right bodysuit can provide bust support and a smooth silhouette in one, and you’ll find increasingly clever cuts designed to work beneath plunging necklines and lower backs without being detected.  

For close-fitting dresses, a mid-thigh style is handy for smoothing the hips and avoiding visible brief lines. And while it may not be the most glamorous consideration, look for styles with popper fastenings - you’ll be grateful for them several hours into the day. 

 

We recommend: Skims (choose your size according to the level of compression you want) and The Pantry Underwear. For a premium made-to-measure option, Rigby & Peller offers beautiful bespoke bodysuits.

Seamless knickers

Best for: fitted, sheer or lightweight wedding dresses

 

Sometimes, it’s not traditional shapewear you need - rather, just a really good pair of invisible knickers.

From thongs to high-waisted briefs, the right shape depends on your dress and the amount of coverage you’ll find most comfortable. Look for seamless, laser-cut styles in a shade that disappears against your skin, rather than white or beige. 

Be careful with longer shorts under lightweight dresses, as the hem can show through the fabric. Aimée also recommends wearing your chosen pair before the wedding to soften the fabric around the leg and waistband and allow it to mould more naturally to your body. 

And remember - comfort is paramount, so if you don’t normally wear thongs, for example, your wedding day is probably not the time to experiment. 

 

We recommend: SKIMS, Commando, Spanx (especially the undie-tectable thong)

Adhesive bras

Best for: backless and strapless dresses where conventional bra straps would be visible 

 

An adhesive bra is a great option for coverage and some support without the straps and back band of a traditional bra. 

The fabric of your dress is worth bearing in mind here - more substantial materials such as brocade, duchesse satin and mikado are generally more forgiving than very fine, fluid fabrics like silk, where the outline is more likely to be visible. 

A good tip is to test wearing an adhesive bra in advance - take it to your fitting to see how it fits and feels before making a decision. On the day, apply it to completely clean, dry skin and avoid body moisturiser or body oil beforehand to give it the best chance of staying put. 

 

We recommend: The Pantry Underwear, Fashion Forms, Club L

Nipple covers

Best for: going braless under dresses that don’t require bust support (but avoiding perky nips)

 

When it comes to nipple covers, there isn’t one universal style that works for everyone - we all have different nipple shapes and colours, so it’s worth trialling a few options before the big day. 

Silicone covers tend to offer more coverage, while fabric options can feel lighter. The key is making sure neither the colour nor outline is visible through your dress. 


We recommend: Nippies, Club L, House of CB

Body tape

Best for: plunging necklines, backless gowns and keeping everything exactly where you want it

 

Where an adhesive bra won’t work with the cut of your dress, body or boob tape can step in. Cleverly placed, it can lift, shape and support the bust without any visible straps or cups. Double-sided fashion tape is also worth having in your bridal kit for securing straps, necklines and any other areas of your dress prone to gaping.  

 

The golden rule? Don’t try it for the first time on the morning of your wedding. Have a practice run with the dress beforehand to perfect the placement, make sure it feels comfortable and check it stays put as you move.
