Tie-front top in crepe de chine

Even though I really want to love the top but I can’t . The fit is really odd. I wear size 8 or 10 on J Crew tops always and size 10 on fitted dress for J Crew. So I ordered size 10 and it is way too small. The other top (size M)I ordered with this top fits well. Maybe this top is not adequately designed.
