Thanks!
Vectoring is actually pretty fun so you can expect more.
As for your 'request,' BSoD… let's just stick to traces for now…
I don't want to get too crazy this early.

Most of the outfits on the show are very contextual and a major part of 'setting the scene.'
(Cowboy hats in Appaloosa, suits and dresses in Canterlot, etc.)
For that reason alone, I think some kinds of bathing suits at the beach would be reasonable.
Obviously, nothing saucy, but I could see something like this (Rarity is probably cutting it a bit close):
Plus, as pointed out by others, the show has made references to 'covering up' in Fluttershy's bed scene and Dash's Parasprite bikini, so swimsuits would allow for another dip into that comedy well.
