Common Bra Fit Issues — and How to Solve Them

Common Bra Fit Issues — and How to Solve Them


At ThirdLove, our goal is to help women everywhere find their perfect bra fit — but we know it’s not always that simple. On top of having to consider your own unique breast shape, there are many common fit issues that can determine which bras are best for you.

Ever experienced bra fit issues? Read on as we identify some of the most common ones (and their solutions) to help you find your perfect size the next time you go bra shopping. If you would like some more help, take our Fitting Room Quiz to find your perfect size and fit in just a few minutes!

 

Do your bra straps slip off?

To fix slipping straps, try tightening your bra straps if you haven’t already. Straps can stretch out over time, so we suggest doing this every other month or so.

If tightening your straps doesn’t do the trick, take a look at the style of bra you’re wearing. Did you know that certain styles (Full Coverage and T-Shirt style bras) typically have narrow-set straps that help keep them on your shoulders throughout the day? Other styles, like Balconette and Plunge bras, have wider-set straps and can slip more easily depending on your body type. Take a look at our Bra Style Guide to identify the style you should be wearing.

 

Are your bra straps digging in?

Contrary to popular belief, your bra straps should not be doing all of the heavy lifting — your bra brand should be doing most of the work. If your straps are digging into your shoulders, chances are your band is too big or has stretched out over time. If this is happening to you, consider buying one band size smaller – that might do the trick. (Remember: if you buy a smaller band size than usual, you need to go up one size in your cup. Example, if you’re currently a 36C, your tighter band would be 34D. View our Size Chart to learn more!)

Lastly, if you’re a D cup or bigger, we suggest buying a style of bra with narrower straps, like our 24/7® Perfect Coverage Bra, so that the straps are centered on your shoulders and the weight of your breasts is evenly distributed.

 

What about gaping bra cups?

This is a common issue for women with East West, Asymmetric, Bell Shape, or Slender breast shapes (check out our Breast Shape Dictionary to identify your breast shape). Typically, these women’s breasts rest at the bottom of their cups, leaving room at the top for cup gaping.

If your bra gaps at the top of the cup, try tightening your bra straps. If that doesn’t work, go down a cup size — your cup may be a little too big. If you don’t think you’re an entire cup size smaller, consider one of our half-cup sizes (our Fitting Room quiz can help you identify if half-sizes may be right for you).

If your cups fit well but there’s still room at the top for gaping, consider a plunge or a push-up style to push your breasts upwards. These cups tend to be cut a little smaller to reduce gaping in the first place.

 

If you have bra cup side overflow, we can help.

Ever had your breasts spill out of the sides of a cup? That’s a surefire sign that your cups are too small. This is probably the easiest bra fit issue to fix — just size up in the cup.

Or, if your band doesn’t feel tight enough, you might need to size up in the cup and down in the band. A snug band will pull the wire in your bra back, and allow your breasts to sit in the cup where they belong.

Here’s how to deal with cup overflow:

If your breasts are spilling out of the bra cup, you’re not wearing the correct size. Similar to side overflow, cup overflow is easy to fix: trade-in for a bigger cup size and give your breasts some much-needed breathing room! If you’re a 34B, trade up a half-size to 34B ½ or a whole cup size to 34C if you need it. You (and your breasts) will breathe a sigh of relief.

 

Wire sitting on your breasts? It shouldn’t be.

Sometimes, we speak to women whose wires are sitting on their breast tissue. This is a sign of your band being too big — you need to invest in a smaller band size to tighten the fit. (Remember: if you size down in band size, you need to go up in cup size, so that your breasts still have room to breathe. For more information on how this works, check out our Size Chart.)
