Pool Party\BBQ Party

I would like a pool party or BBQ party added to the throw party option. I would also like for the guest to show up in swimwear. I love throwing summer parties but all the guests show up in the party wear and it throws everything off. I mean who shows up to a BBQ in a fancy party dress. I also want them to be focused on eating BBQ and swimming and sitting and chatting outside and not in the living room.

If you guys do not wish to add anymore parties, please add an option for us to chose the attire for the party.
