Personally, the crop top. It's not objectively superior or anything, I just credit this red haired vixen with my tummy fetish 'awakening' if you will, since I was 13 when I got the original Ruby version shortly after release. So, it's mostly nostalgia for the sexy, tall, full figured, tummy queen's original design.
Spoilering this because somewhat off topic, but being 13 during gen 3 is likely why I see pokegirls as patrician taste. The anime enamoured me to May, with her full breasts, round ass squeezed into spats, and hips that babies could slide out of were also a reason my penis remembers gen 3 fondly, and was some of the first porn I searched for on the old AOL internet
