These low impact sports bras/bralettes are so comfortable, and have soft double straps, and could certainly be worn as a crop top outside or for yoga, etc. They have no fastenings, just pull on. Very stretchy. Unfortunately my 36Cs are just a little bit too big for them, so it would suit 34 B, C or 36 A B, I would have thought. Only worn a few times, so in really good condition, I did remove the name labels though. Retails for $29.95 each on Gap.com, still available. Would be cute worn out with jeans and a crisp white shirt open, just tied at the waist.
