Last summer friend was wearing fishnet top.. with big holes.. so no nip coverage... no problem.... same night Jenn's dress kept riding up and up... ok.. there may have been help , and security came by to warn us that she had on NO bikini.... as long as it stayed in the general area.. it was fine.. when the dress got up past her belly button.. they gave us a warningartyhorn:
how skimpy? from our experience very skimpy works fine......cover the goodies and make even a half assed attempt to cover your nipples and you'll be fine
