I bought a size larger than normal (kinda between XS and S but normally XS would suffice) as I wanted something slightly loose fit, and also I think due to availability.
I haven't worn it to exercise yet but it's sooooo nice on skin for daily wear!
Just that there was a bit of chemical-like/ plastic smell when it arrived - not sure if that was from the tank or packaging, but it disappeared after first wash.
