I am considering buying a bridesmaid dress on Tradesy.com. Do any of you have any experience with this site, good or bad? I'm wondering if this is a legit site. Is there a difference between buying a used dress from a private seller vs buying a new dress from one of the "boutiques" selling through the site? I found a dress that would be perfect if it truly is as advertised, but I'm wondering if the selling "boutique" could be a knock-off maker from China. It says that it ships from the USA and I googled around and didn't find much. With the "no return" policy, I thought I would ask before I took the plunge and ordered it. Any experiences or advice that you have would be helpful. Thanks!
