What is a waterbra?

It’s a bra that has a water-like gel in it. to make girls look ‘fuller’.

It’s a bra that has a bag of water in it so that your breast appear larger :) Don’t really recommend it though because it might pop.

just like the other responses. its a bra that has like small water bags on the inside to make you look fuller and bigger, but there is a high chance of it popping..which would be bad.
