I've ordered a few things over the years and the quality has always been top notch.
A slight caveat - the items don't always look the same in real life as they do in the illustrations. They're usually very nice, but may hang a little differently than you expect, and sometimes the colors can be slightly different IRL. Also, the sizing can be a little hard to judge since they're not the usual brands many of us know. I would suggest calling and asking for measurements. They have pretty good customer service. The other thing is, it can be a little difficult to return things. They sort of disappear into a black hole for a while (they don't seem to be as automated as the larger companies.) However, I've never had a problem - eventually the return gets credited, but it does take a while.
Given all of that, the items themselves are usually very good quality. I bought my husband a few shirts two years ago, and they're great. And I still have a classic "riding" blazer I bought over 20 years ago!
