Okay, XS just revived itself in my book with their Sunday Night Swim events. On Sunday nights, swim wear and swimming in the pool is encouraged. I love that I can be swimming and lounging poolside in my bikini at 3 am. They close the indoor part of the club and only the outside is available. The music is House/Techno and they have cuban-esque live trumpet players enhancing the music. I think the Sunday Night Swim has not quite caught on yet because only about 15% of the people were dressed casually while the majority of the crowd was dressed up in typical club gear. I could tell the people dressed up were envious of those of us dressed in swim suits because even at 2 am, it's hot in Vegas. It felt so good to jump in the pool. XS is too crowded for my taste on Fridays and Saturdays but Sunday was perfect. There were a lot of people but it wasn't a sardine can. I can't wait to go to Sunday Night Swim again.
Oh, and yes, as absurd as it may seem, get dressed up to go swimming. Bikini with sky high heels, full make-up, and jewelry is a-ok in Vegas and it feels so good to look that hot.
