Finish off the weekend at the Cosmopolitan Hotel at Marquee with special events and... 
If you missed out on attending Shark Week at XS Nightclub you definitely missed out on some Vegas fun. The property completely transformed the venue into an underwater paradise filled with shark sanctuaries and shark swim party fun. Many groups attended on our club guest list and were treated to LED sharks and a unique party that the Wynn/Encore are known for. Waitresses applied bubbles into the air, and for Sunday's event groups of course were encouraged to party in the pool. Be on the lookout for next season's event as you won't want to miss out.
So you are ready to attend one of the night time pool parties in Las Vegas. Whether it is Nightswim at XS on Sundays, Encore Beach Club (EBC at Night), or Drais Swim Night, you will definitely want to know what attire is allowed. The thing everyone needs to know is that these events truly are pool parties. So that means you can wear and bring the same things you would for the dayclubs and pools during the day in Vegas. Guests are invited and encouraged to be in the water. So yes the following items are allowed:
If we had to make one recommendation it would be for men to wear swim trunks and a shirt or a tank top, and ladies with swimsuits or cover-ups over swim attire. Sandals, sneakers, and heels or wedges are also all allowed. Small bags and purses are definitely allowed, but be aware they will be searched by security at the entrance. Make sure to not bring any liquids or medication as they will most likely be confiscated. If you don't feel like wearing pool attire. Standard nightclub dress attire is also accepted.
As for items that don't meet the dress code for night pool party events see below:
Remember you will have to walk through the casino before and after the club, so the hotel property requires men to have shirts and women to have cover up material.
