I've only gotten two boxes from StitchFix so far and have bought one item from each box. I would have bought two out of each box if they fit. It's like Christmas every time I get a new box, and I love surprises, as well as trying things I normally wouldn't even look at in the store.
My problem: I don't think the stylists who work there actually get to look at the clothing up close and personal. I said I don't like floppy, shapeless tops and I've gotten two shapeless tops and one shapeless sweater thus far. It seems like they shop from a website, if there are even stylists. Who knows? It could be some database deciding what to put in your box.
Every box, I've gone back and changed my profile a bit to add more details, and have been consistently adding things to the Pinterest page I linked them to. It seems to be working. The second box was a little more spot-on than the first.
Either way, it's fun and I love the items I've purchased. Worth it if you end up getting at least one item and if you like the lottery, it's worth the risk of possibly losing $20 a month.
*PS They do charge your account the $20 about 7-8 days before your fix is due to arrive, so be aware of that. Sizing is pretty true to measurement, so be sure to get your measurements and sizes right. You can't exchange an item you like for a different size, unfortunately.*
Bottom Line: Yes, I would recommend this to a friend
