I've occasionally gone to bat for Rousteing in the past when I've liked his stuff, but this is beyond unforgivable. Overdesigned doesn't begin to describe these clothes, but not in that fun, intentionally over the top and deliberately tacky/flashy way that designers like Versace, Cavalli, D&G (in their prime, RIP), even Fausto Puglisi manage to pull off. They get a pass to do exactly that sort of too-muchness because of the fact that they seem completely self aware and irreverent about it. Plus, they more often than not manage to flatter at least the models they dress if not real, averagely proportioned women.
This just reads as someone who is rather earnest about it all. There's no sense of humor or fun about it at all, and furthermore, many of the results just end up not simply tacky or vulgar, but ugly.
