I can't believe what I'm seeing on this site regarding the issues that folks are having! I've been receiving SF boxes for about 3 years and I've never had a bad experience with them. Some of the styles have been a miss, but I've never had any issue with returns. I've even changed my address without a problem.
I always review my Fix before it ships and refuse the items I don't want and check the appropriate feedback. The items that I've kept have become my wardrobe go-to pieces.
After reading all these reviews, I'll certainly be on my guard - but so far SF has not given me reason for concern.
