Product Details

This strapless bra stays put all night, so you can stop tugging at your neckline and actually enjoy the party. It naturally boosts and shapes without heavy padding, and it keeps its promise: never falls down, always up for fun.

  • No-slip silicone grip: Silicone lines both the top and bottom edges, so the bra holds its place against your skin instead of sliding down.
  • Wide supportive band: A wide band anchors around your ribcage, giving you a strapless bra that stays up from the base.
  • Supportive foam cups: The cups lift without spilling, so you're not adjusting the top edge every time you sit down.
  • Underwire frame: A wired structure holds each cup's shape, so you get real support with no straps on your shoulders.
  • Removable straps, 2 sets included: Wear it strapless or add straps for multi-way wear, so one convertible bra covers more of your closet.
  • Exclusive half cup sizes: Half cups let you fine-tune your fit between full sizes, so you don't have to settle for "close enough."
  • Stretch nylon blend: The 76% nylon and 24% spandex fabric stretches with you as you move.

Reach for this nude strapless bra under a wedding gown, an off-shoulder top, or a white dress. Its tan neutral shows through less than bright white.

Size & Fit
  • True to size
  • Moderate coverage
  • Bands run 32–44 and cups AA–H with half cups, so it works as a strapless bra for large bust or smaller fits (sizes vary by band). It's true to size with moderate coverage, and it should feel snugger than a bra with straps, since the band carries the support. If you're between sizes, size down in the band and up in the cup to keep your cup volume, or take the Fit Quiz.
Bra Size Calculator & Chart

Thirdlove offers over 60 bra sizes from 32 to 44 band and bra cup sizes from AA to H cup, including our exclusive half cup sizes. Using your current bra size as a starting point, you can refer to the bra cup size chart below to refine your fit.

Bra Size Calculator & Chart

How To Use The Bra Size Chart

When using the chart to find your bra size, keep in mind:

  • The band size increases as you move from left to right. Move left or right within the row if your band doesn't fit.
  • The cup size increases as you move from top to bottom on the chart. Move up or down the columns if your cups don't fit. In between cup sizes? Go up or down a half-cup! And keep in mind if you want styles that are full coverage or not!
  • Bra sizes that share a row are sister sizes, meaning they share the same cup volume (though they have different cup letters). For example, at a glance they’re all just different bra sizes. However, the row with bra sizes 36C, 38B, and 40A have something in common: they all have the same cup volume but have different band sizes. The same goes for the row with bra sizes 38H, 40G, 42F, 44E, 46D, and 48C.
Bra Size Calculator & Chart

Measure snugly around your rib cage (underbust) and around the fullest part of your bust, in inches. Step 1 gives your band. For step 2, subtract your underbust from your bust and find the difference in your band's column. These are the sizes our Bra Size Calculator gives.

Step 1: Band size by underbust measurement (inches). Each range excludes its lower value and includes its upper value.
Underbust (in) Band size
24.9 – 28.5 30
28.5 – 30.5 32
30.5 – 32.5 34

34.5 – 36.5 38
36.5 – 38.5 40
38.5 – 40.5 42
40.5 – 42.5 44
Step 2: Bra size by band and by bust minus underbust (inches). Each range excludes its lower value and includes its upper value.

* Also the result when the difference is exactly 2.5 in: 30B, 32A, 34AA; 4 in: 36A; 5 in: 38A; 7 in: 40B; 8 in: 42B; 9 in: 44B.

The calculator only gives a size for an underbust over 24.9 in, up to 42.5 in, with a difference of up to 13 in. Blank cells and measurements outside these ranges have no size in the calculator.

    Pretty good

    This bra is pretty good once you get it on. It's a little tricky to get on and in place because there is so much silicone grip (which is obviously great so it stays in place!) but getting it on is kind of a pain. To me it seems to run a little bit small in the band.

    Is it a sizing issue?

    The 24/7 classic t-shirt bra is my absolute go-to, so I figured this would be an easy pivot since I needed a strapless. But for some reason, I couldn't get the sizing right. Ordered my regular t-shirt bra cup size, but it gapped quite a bit. I sized down a 1/2 size, but the problem got worse! Sadly, I gave up.

    The perfect fitting strapless bra

    This bra fits well, doesn't have top gape like pretty much every other strapless bra I've tried. I would love it in a slightly lower cut version (but maintaining the bottom support so still not cup gape), but overall it's fantastic.

    Strapless bras are tough for a larger chest, but this bra makes it much easier and more comfortable!

    Always hard to find good,

    Always hard to find good, comfortable bras and strapless is an extra hassle. This bras has really good grip, right size for me and pretty comfortable. A little more difficult to get on because you cant latch in the front and then turn it around because the grip is that solid. So takes some practice, but I like it.

FAQs

Will this strapless bra actually stay up if I have a large bust?

Yes, when you're in the right size. No-slip silicone grip on the top and bottom edges holds it against your skin, while the wide supportive band does the job straps usually do. With bands up to 44 and cups up to H, including half cups, you can get a snug fit instead of a close one.

Should I size up or down for a strapless bra?

Size down in the band if you're between sizes. Without straps, your band holds everything up, so it should feel snugger than your everyday bras. When you go down a band, go up a cup to keep the same cup volume (for example, a 36C becomes a 34D). If you're unsure, take the Fit Quiz or chat with a fit stylist.

What bra should I wear under a strapless or wedding dress?

Choose a strapless bra with grip on both edges and a firm band, since you'll be hugging, dancing, and sitting for hours. This one gives you both, plus wired foam cups that hold their shape under a fitted bodice. Try it on with your dress before the day to check how the neckline sits.

What color bra is best under a white dress?

A nude shade close to your skin tone usually shows through less than a white bra does. Taupe is a tan neutral, so it's a strong pick under white, ivory, and other light fabrics if it's near your skin tone.

Can I wear it with straps, and how many ways can I wear it?

Yes. It comes with 2 sets of removable straps, so you can wear it strapless or add straps for multi-way wear. That makes it a convertible bra you can switch up for strapless dresses, off-shoulder tops, and everyday outfits.

Is it underwire or wireless, and how much padding does it have?

It's an underwire bra with supportive foam cups. The foam gives you a natural boost and shape without heavy padding. Coverage is moderate, so you get a lifted shape without a full-coverage cup.

How do I wash the 24/7® Classic Strapless Bra?

Machine wash it cold in a lingerie bag, then lay it flat to dry. You don't need to hand wash it. The fabric is 76% nylon and 24% spandex.
