This is a yoga bra made of thick fabric, and it doesn't have cups. I wore it without any issues. It's simple to wear. I'm selling this because it's become too big for me, and I've been storing it at home. It measures a little over 30 centimeters when laid flat. I was able to wear it at 156cm and 58kg. It's a size M, but it might be too big for those with a slender build.
