First of all, this site will only give you knock-offs of designer gowns. Whenever you first discover Micwell, it seems that the site is, well, legit. My experience was not as painful as most. I ordered my dress two and a half months before prom. I decided to get it in claret (dark red). I was worried that it wasn't going to get here in time. I tried calling the number, but it was bogus. Then I emailed them and kept emailing them for an update on the dress. Eventually I received a response. It finally arrived 2 weeks before my prom and I had to get it altered, pronto. It was too long and too big, even though I put in precise measurements on the Micwell site. My dress didn't look horrible. It actually looked great. It had a few differences from the picture, but nothing major. The color was a little off and the stitching could have been better. I think it didn't come out terrible because I ordered a simple design. After I wore it to prom, a few of the beads were loosening up, but that's pretty much the only problem I had with the dress.
My sister's dress was a different story. Well, same shipping story, but different outcomes. Her dress did not look like the picture and the built-in-support of that dress was lop-sided.
In my honest opinion, don't buy from Micwell (which is AKA Made-In-China Well). It is a huge risk. The prices might be great in all, but you get what you pay for. You would save more money buying a dress from a certified prom store. But if you're looking to save money or to find a last minute dress, I suggest you use Rent the Runway. Google that store and you'll get even better quality dresses that will come in on time. I used that site for my second prom. Don't give your business to Micwell because of the high risk and the scam that you could fall into.
