I have used Everlane four or five times over the last couple of years. Delivery times to Scotland have been exceptionally good (5 days being the typical norm).
The quality of clothing has been solid, but not up there with the best (but then again, Everlane don't charge top prices).
Worthy of mention would be my Parka. I got it in the sale, and I consider it to be an absolute bargain when compared to other jackets that I own (all of which cost at least three times as much).
