Kelly, I've had experience with one Olivia Moon item - a blouse I ordered from Nordies last year. If I recall, the large was supposed to be 12-14, and the size chart indicated I was a 12. I ordered the large and it was much too small - so small I thought it may have been mis-sized. I returned it and didn't re-order. I hope others chime in, because I've been tempted to try other OM tops, but the sizing issue has kind of put me off.
