Apparently there's a lot of different terms...

Trunks for men, cozzies for women. (You can also prefix 'swimming' to either of those words to make it clearer).

As for soft drinks; probably 'soft drinks' or the specific type. 'Pop' as a child in the north of England.

Definitely bathers for women - and boardies or Speedos for men, depending on type (although they'd be bathers too).
