I love the print haven’t tested weather or not it’s reactive to black light. For ordering I found the measurements difficult. I usually buy the same size in both top and bottom and ordered accordingly. For this bikini, I needed up repurchasing the bikini top in the next size up, and would have liked the bottom in a down size but did not repurchase as I could manage. Too has not support, so if your particular about breast support this bikini could be too revealing for your taste.
