Sexy x criss cross back deep v lululemon tank top

Where is the size for these? Didn’t see in bra pad slit… would say fits like a 4 or 6 bra on top and then open bottom can leave open or pull to tighten. I’m a 32B and this is very supportive for exercises with jumping/running. Can add the pads for extra oomph but don’t need. Very sexy flattering cut in a silky black.
