There's nothing that better accentuates plump thighs like a nice, tight pair of thigh-high socks. Not only will they keep you warm, but they'll also give your look a bit of a boost thanks to the slight bulge that forms around the hem. For some creators, this bulge is a beautiful focal point that highlights the suppleness of their characters' skin.
Rin Tohsaka (from the Fate franchise) is almost always seen rocking a pair of thigh-high socks that gently caress her shapely legs.
