Quick Answer
Measure your underbust and full bust with a soft tape, then match those numbers to each product's own size chart rather than assuming your bra size carries over. If you fall between two sizes, size up for comfort in pull-on styles and stay true to size in styles with adjustable straps or ties. The right bralette should feel snug but never leave deep marks or require constant readjusting.
Bralette sizing trips up even people who know their bra size cold, because bralettes don't follow the same rules. There's no underwire, no molded cup, and often no hook-and-eye closure, so the fit depends almost entirely on stretch and how the band sits against your ribcage.
Below are the questions we hear most often, answered one at a time so you can jump to the one that matches your situation instead of reading a full sizing lecture.
Do I use my regular bra size for a bralette?
Not automatically. Your bra size is a starting point, but bralettes are sized by their own charts, and those charts vary by style. A bralette with adjustable straps and a hook closure will fit closer to your bra size, while a pull-on lace style usually relies on stretch to cover a range of cup sizes.
Check the specific product's size chart before ordering. For example, Minimal Lace lists S as 32B, 34A, and 34B, and M as 34B, 36A, and 36B, which shows how much overlap exists between sizes in a stretch lace design. If your measurements land in two rows, that's normal, not a sign you measured wrong.

- Always use the size chart on the product page, not a generic brand-wide chart.
- If your band size and cup size point to different rows, prioritize the band measurement for comfort.
How do I measure myself at home without guessing?
Wear an unlined bra or nothing at all, stand relaxed, and keep the tape level around your body. Measure your underbust first, snug against your ribcage, then measure your full bust at the fullest point. Write both numbers down before you start comparing them to a chart.
The underbust measurement usually decides your size row, because that's where the band does its work. The bust measurement tells you whether you need more coverage or stretch. If the two numbers suggest different sizes, go with the one that matches your underbust and let the fabric's stretch handle the rest.
- Keep the tape parallel to the floor, not angled up your back.
- Measure at the end of a normal breath, not a deep inhale.
What if I'm between two sizes?
It depends on the closure. In a pull-on bralette with no adjustability, size up, because a too-tight band is the most common cause of discomfort and digging. In a style with adjustable straps, ties, or a hook-and-eye back, you have more room to fine-tune, so you can often stay with your measured size.
Fabric content matters here too. A blend with more spandex, like the 92% nylon and 8% spandex in Minimal Lace, will stretch and recover better than a mostly rigid lace, which means it can comfortably cover a slightly wider size range.
- Pull-on style: size up when in doubt.
- Adjustable style: stay true to your measured size first.
How tight should the band actually feel?
Snug enough that it stays in place when you raise your arms, but loose enough that you can slide two fingers under the band without forcing them. If you can see red indentations after ten minutes, it's too tight. If the band rides up your back when you lift your arms, it's too loose.
your arms
Remember that stretch lace relaxes slightly with body heat and movement. A band that feels borderline tight when you first put it on will usually settle into comfortable within a few minutes, so don't judge the fit in the first thirty seconds.
- Test the band by reaching overhead and twisting gently side to side.
- If the band rolls or folds, it's likely too loose rather than too tight.
Why does my bralette dig in or ride up?
Digging usually means the band is too small or the straps are carrying too much weight. Riding up usually means the band is too large, so it can't anchor against your ribcage. Both problems are sizing issues more often than design flaws.
If you're between sizes and experiencing either problem, try the adjacent size before assuming the style won't work for you. Adjustable straps and back closures give you a middle ground that pull-on styles can't offer.
- Loosen straps slightly if the band is doing its job; the band should carry most of the support.
- If a band rolls consistently, try one size down in a style with a hook closure.
Do bralette sizes match bodysuits and corsets?
No, and this is where a lot of returns happen. Bodysuits, corsets, and bralettes each have their own size charts even within the same store. A size S in a bralette won't necessarily match a size S in a corset, because corsets are structured and sized by waist and bust measurements with specific ranges.
For example, https://thebralettecoenc.com/products/in-the-moonlight-corset-1-5a5a814c3845ca7bfb0113b6-1494783In The Moonlight Corset lists XS as US 2 with a 29.9-33.1 inch bust and 23.6-26.8 inch waist, while a bralette size S covers a different range entirely. Always check the chart for the specific garment type you're buying.
- Treat every product category as its own sizing system.
- When buying a set, check both pieces' charts separately.
Can I return a bralette if the size is wrong?
At The Bralette Co., unworn bralettes may be returned or exchanged within 14 days of purchase. That window is your safety net if the size chart and your measurements didn't quite line up.
To keep your options open, try the bralette on over a thin camisole or keep the tags attached until you've confirmed the fit. Once it's been worn against the skin, the return option typically closes.
- Keep tags on until you've done a proper fit test.
- Check the return window before ordering multiple sizes to compare.
Bralette Sizing FAQ Cheat Sheet
Measuring
Measure underbust and full bust with a soft tape, keeping it level. Use the underbust to pick your size row. Write both numbers down before opening any size chart.
Between sizes
Size up in pull-on styles with no adjustability; stay true to size in styles with adjustable straps or hook closures. Check the closure type before deciding.
Band fit test
You should fit two fingers under the band, and it shouldn't ride up when you raise your arms. If it fails either test, try the adjacent size.
Returns
Unworn bralettes can be returned or exchanged within 14 days at The Bralette Co. Keep tags on until you've confirmed the fit.
Sizing Details Worth Knowing
- Minimal Lace: 92% nylon, 8% spandex; available in Black and Dusty Rose; S fits 32B, 34A, 34B; M fits 34B, 36A, 36B; L fits 36B, 38A, 38B; unworn bralettes may be returned or exchanged within 14 days. The high spandex content means this style stretches and recovers well, so the overlapping size ranges are genuinely wearable rather than just on paper.
- In The Moonlight Corset: Size XS is US 2 with a 15.4 inch length, 29.9-33.1 inch bust, and 23.6-26.8 inch waist; sizes run XS through XL. Corsets are sized by structured bust and waist ranges, not bralette sizing, so you need to measure separately even if you know your bralette size.
- Sweet Nothings Cami Top & Shorts Set: Size S has a 13.4 inch top length, 9.8 inch shorts length, 25.6-43.3 inch bust, and 23.6-41.7 inch waist; sizes run S through L. The wide bust and waist ranges show this set relies on stretch, so your usual size is likely to work even if your measurements sit at the edge of a range.
Bralette sizing gets easier once you stop translating from your bra size and start using each product's own chart. Measure yourself, check the specific style's range, and use the band test to confirm. If it's not quite right, the 14-day return window on unworn bralettes gives you room to try again.
