This makes the assumption most know many gothic lolita outfits lol
tl;dr,
gothic lolita, the name is self explanatory. It's not just gothic French maid like outfits, but it's meant to give us an impression of youth (which is why it's cringy).
2B's is like if Alexander McQueen had a take on gothic lolita during his London collection ~~ it's sexy, for a grown woman. The visible panties isn't the sexy part, it's the fact that the outfit has a space to show off the upper thigh. The skirt is long at the front, but short on the sides.
It's not something for lolita to wear. Especially since it has a display for cleavage but by means of a pattern.
I dunno, from the little I know about fashion from being dragged to every exhibition and looking at the shit people wear in Harajuku, 2B's outfit is like a goddamn revolution in a genre that's quite frankly, usually distasteful.
If it weren't from a game and was part of a collection, I think it would get a lot of praise by outlets.
