Amazon look for less for my favorite cardigan! Here’s how they compare: The Amazon version looks similar. It’s longer and the sizing is more limited so I wasn’t as able to get as close of a fit (im wearing a small). It doesn’t have any wool so it’s not as warm and because of that it’s also thicker because of that. The j crew version has more sizing options. I sized down 2 sized for a closer fit (wearing an XXS). It’s 35% wool and 35% cotton so it’s much warmer without the bulk
