Signs That Help You Determine That Your Sports Bra Is Tight

Naturally, a sports bra should fit so well so that you do not get an unnecessary bounce in your chest region since you mostly put them on for sports or to hit the gym.

However, in the bid to get optimum support from the bra, the tightness gets to the extreme at times. 

The following red flags will let you know when your bra is too tight:

  • The band of the sports bra leaves glaring marks on your body
  • Your cups overflow .i.e. bra spillage
  • The cups, bands, or straps dig into your skin
  • The band rides up on your chest rather than stay under your bust
  • Your ribs hurt 
  • You have difficulty in breathing

When you notice any of these signs, it is time to take a decision- trash it or, better still, stretch out the bra.

How To Stretch Out A Sports Bra

Just so you know, stretching out as an option comes from the point that over time, our bras stretch as a result of wearing them a couple of times. 

But you do not want to bear all the inconvenience that comes with wearing a tight bra for that long before you get the issue fixed.

Sports bras come in different fabrics, but mostly in cotton and polyester, hence we will have a look at how to stretch out a sports bra made of cotton and polyester.

Let us begin.

  1. How To Stretch Out A Sports Bra Made Of Polyester

Due to the rigid nature of polyester, it is often used in making sports bras. Sometimes, stretchy fabrics are used like elastic or fabrics that are a bit stretchy so that they can easily return to their original states after a stretch.

To make this happen, there are two approaches- either you make the spandex weak or enlarge the bra itself.

Whichever you choose to achieve, the following guide will help you:

  • Set the bra to wash in a heat revolution for approximately half an hour.
  • Spread it to dry while it is still warm and soggy
  • Stretch the bra on the clothing line and secure it at both ends with pegs. You can also decide to stretch it with an iron that steams- you iron as you extend the bra. Another way to stretch the bra is to put it on while it is still damp, to make it conform to your actual size.
  • Whichever method of stretching you choose, leave the bra to dry.
  • If you do not get the desired result with the first attempt, then repeat the process until you get what you want.
  1. How To Stretch Out A Sports Bra Made Of Cotton

It is expected that a cotton sports bra which was not shrunk during production will shrink after you wash it a few times.

Even so, you can slacken the cotton fibers of the sports bra to the size you want. Here is how to do that:

  • Create a mixture of shampoo or conditioner (about 15ml) and a liter of warm water in a bowl. Ensure you stir enough until you have a blended solution.
  • Throw in your sports bra and allow it to soak for half an hour.
  • Remove and squeeze out water
  • Wrap the sports bra in a dry towel, roll both so that the towel absorbs whatever water is left in the bra.
  • Stretch out the bra to desired size. You can use an old bra as a yardstick.
  • Rinse off the bra in warm water and hang to dry. You can stretch out the bra on the clothing line and hold it in place with pegs till it dries up.

And there you are!
