My main reason for not trying Stitch Fix is the cost. Even if they sent me something I loved, it's just cost prohibitive on our budget. But that is why I love Twice. I get the fancy name brand clothes I love at a fraction of the cost. And if you use Twice like I do, it can be just like Stitch Fix. The trick for me is to buy a variety of clothes and just assume that I will be making a (free!) return. Plus, you get free shipping if your order is over $50, so I always make sure my order is over $50. I start with things I know I love, like button down shirts from J.Crew and and skirts from Ann Taylor Loft. Then I add things from places I've never tried, but always wanted to - like Anthropology and Calvin Klein.
And sometimes I end up with awesome. Like my new favorite dress, from Anthropology for $25!
If you want to try Twice, use my link and we'll both get $10 off! Be bold and see what you find!
