Bra Fit Guide
Try on your favorite underwire bra now, then use the below as your guide.
Step 1: The Band
Your bra’s band provides most of its support (not the straps). Most women are wearing a band that’s too loose.
Your band should lay straight around your body, beneath your shoulder blades. If you’re able to pull your band more than two inches away from your back on the tightest hook, or if the band slides up your back, try a smaller band size.
Step 2: The Cup
Cups that are too big are pretty easy to spot. They wrinkle and gape. Cups that are too small are more common and trickier to recognize. A properly fitting cup holds all of your breast tissue without cutting into you.
If you feel like you’re in between cups, adjusting your straps can help. If you sized down in your band, you’ll need to go up a cup size to stay in the range you’re wearing now. This is called “sister sizing.” For example: a 34D and a 32E are sister sizes.
Step 3: The Wire
A properly fitting underwire bra offers shaping and support that a wireless bra cannot. But an ill-fitting wire can be really uncomfortable. If your wire digs into your side under your armpit, consider a larger cup size. If it digs into your chest, try a larger band size.
Step 4: The Straps
Your straps should be snug against your shoulders and stay in place as you move throughout your day. They should never dig in or feel uncomfortable.
If your straps are digging in, there’s a good chance your band is too big — consider trying a smaller band. If your straps are slipping off your shoulders, try adjusting them for tightness. One side may need more adjustments than the other (your boobs are sisters, not twins).
Not every bra style is perfectly suited to every body type, so it’s about finding the bra that works best for you. If your first CUUP bra doesn’t feel quite right, you can try another size or silhouette. Free returns and exchanges on all bras.Watch our fit video

Note that our bras are unlined and unpadded. If you prefer a more tailored fit, you may want to try one cup size larger and one band size smaller than what you’re already wearing — especially if your current go-to is padded. If you need help, you can schedule a virtual fitting.or
