Pool party would should I wear?
It depends on if it's day or night. Yeah, shorts and a tank top over a bathing suit is appropriate and if it's at night, you could wear a wrap around dress or skirt and the bathing suit or bathing suit top. Now, if you're a girl...just kidding. Guys can wear anything.
I agree with the above...A bathing suit. You will be dressed quit accuratly for a swimming party. Have fun ;)
bikini? haha I would wear shorts and a nice shirt with my bikini underneith.
bathing suit with shorts and a tank top over with matching flip flops
