JoyLab sports bra, blue/gray, size XL

This is a reposh JoyLab sports bra, blue/gray color. I purchased this here as a size M/L, there are no inside tags. I’m listing this as an XL. I wear a size L in Joylab and could deal with it being a little snug if it was on the M side. I believe this is actually an XL. I am thin but have a 34D bust and this is too big for me. The condition is excellent and the color is great, I just can’t make it work for me. Please feel free to ask for any details or additional measurements.
