It's not like the woman was naked. In fact, she was wearing a one-piece, normally considered more conservative than most two-piece swimsuits. I'm thinking some of the more prude, senior, and/or looks-challenged tenants in the complex (either led or egged on by some female) probably had it in for this young woman... and nothing short of a potato sack with holes in it would've been "inappropriate" for them.
