I have ordered from The Real Real 13 times and have had some luck. I really enjoy finding clothing brands that are not readily found at the local mall. I have found some bargains as well. Don't look at the sizes, every brand is different, rather shop by your measurements.
I have had some problems. Sometimes the measurements listed are incorrect. I received a shirt once with no tag. I called the call line and only received store credit. Every clothing item has a tag. If the tag is removed you cannot return the item. Today I received a winter coat where the tag was place directly through the center of the sleeve! I am unable to get my arm into the coat without removing the tag! Finally I received a "new" ST John sweater with original tags. I wore it and found that there were several holes in the sweater! Since the tag was removed The real real gave me $20.00 store credit. This was not fair. While deals are to be found remember that postage for shipping and returns add up.
