How to Solve the Most Common Bra Fit Issues
A great bra should feel like a second skin. Yet, most women (statistically, over 80%!) are wearing the wrong bra size without even realizing it.

An ill-fitting bra doesn’t just make you fidget all day. It can lead to back pain, shoulder strain, poor posture, and even tension headaches. And let’s not forget the confidence boost that comes from wearing something that fits like a dream.
The truth is, common bra fit issues like slipping straps, gaping cups, and digging underwire aren’t just annoying. They can impact your overall comfort and well-being. That’s why knowing your correct size, understanding your breast shape, and getting fitted regularly are essential steps to finding bras that truly support you.
In this guide, we’ll break down the most common bra fit issues, how to fix them, and what to look for when shopping for your perfect fit. It’s time to ditch the discomfort and embrace bras that work for you, not against you.
Identifying and Fixing the Most Common Bra Fit Issues
When your bra fits well, you barely think about it. It just works. But when something’s off? It can ruin your whole day.
Bra fit issues affect nearly everyone at some point, but the good news? They all have solutions.
Bra Straps Slipping Off
One common culprit of slipping straps is a stretched-out bra that’s past its prime (yes, bras have an expiration date). Another issue is that some bra styles have wider-set straps, which may not work for those with narrow or sloping shoulders.
How to Fix it
First, try tightening your straps. Elastic stretches over time, so check on it every few months. If newer bras are slipping, look for alternatives with narrower-set straps (like a full-coverage bra or t-shirt bra). And if your bra is old and stretched out, it’s time to replace it.

This bra is different--the silk lining and organic cotton really make a difference. Plus it's so cute,” Shannon R., a member of the JulieMay community, said.

Bra Straps Digging In
How to Fix It
Go down a band size to get the support where it belongs. But if you go down in band size, go up in cup size (for example, if you’re a 36C, try a 34D.) If you’re a D-cup or larger, opt for bras with wider, cushioned straps for better weight distribution.
Bra Band Riding Up
Your bra band should sit parallel across your back. If it’s riding up, it’s too big, meaning it’s not offering enough support and can lead to a sagging effect.
How to Fix It
Go down a band size and up a cup size to maintain balance. For example, if you’re wearing a 36B and the band is riding up, try a 34C. When you fasten your bra on the loosest hook, the band should feel snug but not constricting.
Bras will stretch over time, so when you buy a bra that fits on its loosest hook, you can wear it for longer. As it stretches, simply go down on the hooks.
Gaping Bra Cups
Cups should sit flush against your breasts without any gaps or puckering. If there’s space at the top, your cups are too big or the bra style doesn’t suit your breast shape. This is especially common for those with shallow breasts or naturally softer tissue.
How to Fix It
Try a push-up style that has shallower cups that prevent gaping. Tightening the straps can also help. If the issue persists, consider half-cup sizes for a more precise fit.
Not Buying for Your Breast Shape
Not all bras fit the same because not all breasts are shaped the same. A full-coverage bra might work for one person but gap for another.
How to Fix It
Identify your breast shape and shop accordingly (it may take a bit of trial and error). If you have fuller sides, opt for plunge bras. If you have shallow upper breasts, push-up styles might be a better match.
Cup Spillage or "Quad Boob" Effect
If your breasts are spilling over the top or sides, your cup is too small. This leads to the dreaded "quad boob" look under clothing, which is not ideal.
How to Fix It
Size up in the cup so your breasts are fully enclosed without being squished. If your band also feels loose, size up in the cup and down in the band (e.g., from 36C to 34D). Side-support and plunge bras are great for redistributing breast tissue toward the center.
Underwire Digging In
A good underwire should sit against your sternum, not on your breast tissue. If it’s poking, pressing, or stabbing, you might be wearing the wrong size.
How to Fix It
Check your fit. If the underwire is sitting on breast tissue, size up in the cup. If it’s still uncomfortable, try a wire-free bra or soft-cup bra for a gentler fit. And if the wire pokes through the bra’s fabric, it’s time to replace it.The Center Gore Bowing Out
The center gore (the piece between your cups) should lay flat against your chest. If it’s floating outward, it likely means your cup size is too small.
How to Fix It
Size up in the cup and check that your band isn’t too tight. A well-fitting bra should hug your ribcage, not float away.
Wearing a New Bra on the Tightest Hook
When you buy a new bra, do you immediately fasten it on the tightest hook? If so, try to avoid doing so. Bras stretch over time, so you want room to adjust.
How to Fix It
Always start on the loosest hook. As your bra naturally stretches, you can tighten it over time.
