I'd like to be able to hit a b&m Uniqlo so I know how their stuff fits me, but as long as the site ends up having a good return/exchange system, that'll be satisfactory.
I usually go check uniqlo.uk since they have measurements on the items which makes proxying stuff from uniqlo easy. I do wonder how badly the site is gonna be wrecked from all the new buyers though. Wonder if they'll have the stock to meet the demand.
