The 6 Signs Of A Supportive And Properly-Sized Bra

According to legendary lingerie brand Victoria’s Secret, 80% of women are currently wearing the wrong bra size? Yup, that means 4 out of 5 of your girlfriends are probably having to deal with an ill-fitted bra that causes discomforts, aches, pains, and more.

A bra’s main function is to provide adequate support to the weight and structure of the breast. Without proper support, you leave yourself susceptible to a myriad of different issues including weakened breast tissue, sagging, drooping, chaffing, and even acid reflux!

When it comes to figuring out if your bra is actually giving you the support you need, there are a number of factors to consider. Today, we explore the 6 signs of a supportive and properly-sized bra, so keep on reading to find out more! 

The Perfect Cup Size

The 6 Signs Of A Supportive And Properly-Sized Bra

The cups of a well-fitted bra should usually sit comfortably against your body, and never dig into your skin or be too loose. The perfect cup size will enclose the whole breast and your bust should not spill out of the bra at the sides or in the middle. On the flip side, there should also be no gaps between your cup and your bust which is often a sign of wearing a bra that is too big. 

To find your perfect cup size, we highly recommend heading to one of your local underwear or lingerie stores that offer professional bra fittings. Alternatively, you can do this at home by following these steps:

  1. Measure under the fullest point of your bust (usually over the nipple).
  2. Make sure the measuring tape sits level and flat; avoid pulling it too tight around your bust. 
  3. Subtract your band size from your measurement and use the resulting number to determine your perfect cup size.

2. The Underwire Doesn’t Cut Into Your Skin

The underwire component of a bra is especially important for individuals who have a bigger bust and require more support. As a general rule, the underwire of your bra should be adjacent to your armpit and the cups should lay flat on your breasts. It should also comfortably contour your breast without digging in or gaping.

Last but not least, the underwire of a properly sized bra will never cut into your skin or cause discomfort, and if this is the case, there is a high chance you are wearing an ill-fitted bra. 

3. The Goldilocks Of Straps

Although the majority of support provided by a bra comes from the cup and underwire, bra straps also play a big role in the overall look and feel of how your bra fits. Bra straps function as an anchor for your bra and help with positioning, lifting, and keeping the cups in place so you ‘spill out’ Straps that are too tight may cause discomfort in the shoulders and back, while straps that are too loose are usually caused by cups that are too large and not filled properly.

In a properly-sized bra, you should be able to fit two fingers easily between your shoulder and the straps of your bra.

4. Your Bra Band Sits Straight

If your bra band is riding up or hanging too low, it’s time for it to go! A properly sized bra will have a bra band that sits straight around your body, without being too loose or cutting into your flesh. A common reason for bra bands riding up are straps that have been shortened – often a means of giving the girls an extra lift or boost, but do note that in the long run, this may lead to back aches, discomfort, chafing, and general discomfort.

The perfectly fitted bra will offer you all the support you need in the cups, without having to hike the band up. 

5. Your Bra Doesn’t Shift When You Raise Your Arms 

The 6 Signs Of A Supportive And Properly-Sized Bra

Do you find that your bra tends to shift or ride up whenever you raise your arms? If so, there is a 99% chance that you’re wearing a bra that is simply too big for you (or has stretched to the point where it needs to be replaced). Aside from being downright uncomfortable and annoying, a bra that rides up can cause unsightly bulges that ruin even the most gorgeous of outfits. 

A bra that fits you well, however, will stay in place no matter how high you raise your arms. This is because the band fits perfectly around your ribcage without being too loose, resulting in a smooth silhouette that is free from annoying bulges and bumps! 

6. There Are No Wrinkles In Your Cup Fabric

Lastly, a well-fitted bra should be free of wrinkles in your cup fabric. If you find that your bra cups crease, pucker, or wrinkle at the tip, chances are the cups are too small because your breast tissue is unable to reach the center of the cup to create a smooth and seamless line. However, if you find that there are wrinkles all over the cup, you are probably wearing a bra size that is too big for you. 

It’s all about finding the perfect balance that results in a smooth, crease-free cup that looks fabulous under your clothing! 


A properly-sized bra that is well constructed and the right size for you is an absolute must for any and every lady. We hope that this article has equipped you with all the knowledge you need to ensure that you find the perfect bra that allows you to say goodbye to chaffing, discomfort, shoulder, neck, and back tension, and more.
