What is the Role of Elastic in Your Bra?

The bra straps carry 10% of your breast weight and keep the bra in a fixed position. It’s the elastic used in the strap that provides some support and comfort. Elastic in your bra is typically shiny on one side and plush on the other. Bras with a smaller upsize have a narrow elastic, and the different types of bra straps, so in this blog, we will learn the purpose of elastic.

Elastic is an essential component of a bra or panty that is a small, narrow loop used to provide support, hold the bra in the right position, create a finished edge, give an aesthetic effect, and add design elements. Elastics are commonly used in bra straps, bands, and wire channels.

Features of Elastic in Your Bra

  • It has the quality of stretching and then returning to its original shape.
  • It is adaptable and gives a perfect fit.
  • The stretch capability and recoverability aid easy movement and make your bra sturdier so that it doesn’t tear or break.

How to Increase the Longevity

If you take proper care and follow the wash-care process, your bra will remain flexible and bounce back to its original shape.

  1. Do not bleach your bra because the pH level of bleach is higher than 7, which reduces the stretchability of the elastic and fails to bounce back to its original shape once stretched out.
  2. Keep your bra away from the dryer and direct sunlight. Always dry your bra in the shade and avoid using the dryer.

You must understand that the elastic in your bra plays a major role in determining the size, shape, and flexibility. If the elastic doesn’t bounce back as it once did, you should throw away the bra and buy a new one.
