Picking the Right Size: How to Find Your Perfect Lingerie Fit

Finding the right size is the first step to feeling good in what you wear. Too tight and you’ll be uncomfortable; too loose and you lose support. Let’s break down the basics so you can get a fit that works for you.

Measure Yourself at Home

Grab a soft measuring tape and stand straight in front of a mirror. First, measure around your ribcage just under the bust. This is your band size. Round the number to the nearest even number – most brands use 30, 32, 34, etc.

Next, measure the fullest part of your bust. Subtract your band measurement from this number. The difference tells you your cup size: 1 inch = A, 2 inches = B, 3 inches = C, and so on. For example, a 34‑band and a 36‑bust difference of 2 inches means a 34B.

Don’t forget to check both sides. Your body isn’t always perfectly symmetrical, and a small adjustment on one side can make a big difference in comfort.

Test the Fit in the Store or Online

If you’re in a shop, try the bra on while it’s still on the rack. The band should sit level and feel snug without digging. You should be able to fit two fingers under the band – that’s the sweet spot.

The cups should fully encase your breasts without spilling over or leaving gaps. If you see any “V” shapes or bulges, the cup is too big. If the fabric rides up, it’s too small.

Straps are not meant to bear most of the weight. Adjust them so they’re firm but not cutting into your shoulders. When you raise your arms, the bra should stay in place.

Shopping online? Use the same measurements and consult each brand’s size chart – they can vary. Look for sites that let you filter by band and cup, and read reviews for real‑world fit notes.

Don’t ignore the material. Stretchy fabrics can give you a little wiggle room, while rigid fabrics need a more precise size. If you’re between sizes, choose the one with a bit more stretch.

Common mistakes include relying on the size on the tag of an old bra, ignoring weight changes, and not re‑measuring after major life events like pregnancy or weight loss. Your body changes, and so should your size.

When it comes to underwear, the same band measurement works for most briefs, thongs, and boyshorts. Look for a snug fit around the hips without pinching. If the fabric folds or rides up, size down.

Finally, give yourself a few minutes to move around in the new pieces. Sit, squat, and walk. If they stay in place and feel comfortable, you’ve nailed the size.

Remember, the goal is confidence. A well‑fitted piece stays hidden under clothes, supports you where it matters, and makes you feel great all day long. Take the time to measure, try, and adjust – your body will thank you.
