@NitroDubs I used to follow some brit account that posted this, every girl they had was a 6 at absolute best. I picked girls from the first page of results that I find quite plain:
Boring, unsexy clothing designed to make a 78 yo granny think it's revealing (while not actually hot or even form fitting)
Plain, pan-faced, large cheeked girls with troonish facial structure, garish and gaudy makeup
Graceless posing. Classic pinups used to be based off boudoir photos, the idea is that she's dressed for seduction and lazing on your wing as if it's a comfy 4-post bed
