I usually wear a small and I ordered a small but this cardigan was a bit big, it always falls off my shoulder. I wasn't sure at first if I wanted to keep it or not because I didn't love it.  THERE'S SO MUCH FABRIC. I used it a few times and since it's been hot and sunny, it was nice to have this cardigan when I went places that were a bit cooler due to A/C in the building or breezy outside.  I guess I'll keep it. :)  I just wish it fit a little better.
