Putting side the outfits where it just looks confusing because the wearer paired warm-weather sandals with chilly-weather long-sleeved coords, the average lolita outfit has covered shoulders, a poofy skirt, a lot of frills and a lot of details. Then when you get to the legs and they're bare, it looks a bit unbalanced, whereas most socks have patterns on them that help balance out a frilly, fancy top portion.
So you'd think, it's ok, just pick a simpler dress with less details so that it's ok for the legs to be bare, right, but head too far in that direction and your outfit suddenly becomes too plain and too simple to be lolita, it starts looking like otome or even retro or hillbilly, instead of lolita.
Tough to find that sweet spot where you don't look overdressed for your bare legs, while still being fancy enough to be lolita.
