Harley, one of the cast of playable characters from the underappreciated Outlaw Sports series of games from the PS2/Xbox era.

Her two outfits are "tube top, denim shorts, cowboy boots" and "bikini top only, pants, belt, cowboy boots"

Edit: Well shit, this came out about a thousand times better than I was expecting from a bunch of PS2 emulator screenshots. I'll have to do more of these characters.
