I love buying things from Milanoo. I can send them my measurements and have something customized or order something in exactly my size. I sent exact measurements for a dress I bought in the japanese lolita style and got exactly what I asked for, and shipping time is pretty good for international (I get my item within about 2 weeks, maybe less). It's a decent price for good quality items. I always check the size chart on things and measure myself to make sure I am giving them correct and up-to-date measurements.
Milanoo is the first website I check when I think of dressing up, whether it's formalwear or cosplay. It's by far my favourite clothing retail website. I am definitely going to be a repeat customer.
