How to Know If Your Bra Is Not Pulling Its Weight

At Wacoal, we firmly believe that you should never have to settle for a badly fitting bra. Your body is a testament to your unique beauty, and irrespective of your breast size, you deserve a bra that makes you feel fantastic every day. The human body and breasts naturally undergo changes over time, so it’s crucial to ensure that your bra keeps up with these transformations. In this article, we’ll explore some key indicators that you might be wearing a poorly fitting bra. If any of these signs resonate with you, it’s time to embark on a shopping journey to discover the bra that you truly deserve.

  1. Skin Irritation and Chafing

If you notice redness, blistering, or persistent itchiness on your skin, it’s a classic sign that your bra is too small. Tight bras cause the fabric to rub against your skin during movement, leading to chafing. This issue is particularly prevalent with ill-fitting sports bras, as they are designed for active use.

  1. Misplaced Underwire

The underwire of your bra should comfortably sit at your underarm level. If it’s digging forward into your breast tissue, it suggests that your cup size is too small, and the underwire is resting on your breasts rather than providing proper support. Conversely, if the underwire is digging into your armpit, it’s likely that your cup size is too large.

  1. Band Riding Up or Breasts Popping Out

If the band of your bra rides up at the back, it’s a clear indication that the bra is too big around your body, and you should consider a smaller band size. On the other hand, if your bra rides up at the front, it may be time to explore different bra styles or types that offer better support. Additionally, if your breasts are spilling out from underneath your bra, it could be due to a loose band or a too-small cup size, necessitating a proper fitting.

  1. Inadequate Cup Coverage

When your breasts bulge out of the cup at the front or sides, it’s a sign that your cup size is too small, and its time to try a larger size. Sometimes, this issue can be influenced by breast shape, making a fuller coverage bra style a more suitable choice than a plunge cut.

  1. Excess Fabric or Gaping Cups

Excess material in your bra cups is a common indicator that your cup size is too large. Gaping at the top of the cup, where you can see the inside of the cup while wearing it, also suggests the need for a smaller cup size. Your breasts should comfortably fill the entire cup. If you have conical or slender breasts, this may also be an indication that you need to explore different bra styles.

Can a Badly Fitting Bra Cause Pain?

While research on the relationship between badly fitting bras and pain is ongoing, there appears to be a connection between the two. The University of Portsmouth highlights that inadequate breast support often leads to breast pain, reported by approximately 50% of women. Ill-fitting bras have also been associated with discomfort such as neck, back, and shoulder pain, poor posture, as well as chafing and itching. Furthermore, an unexpected consequence of wearing an incorrectly fitting bra is a reluctance to engage in physical activities, including exercise.
