I'm sorry ladies but the Medium definitely fits better.
#1 The elastic in that first gather is annoyingly present when I where the Small... and it doesn't bother me at all in the Medium.
#2 Keep in mind these haven't been washed or dried yet and I really don't feel any room for shrinkage in that Small one.
Unfortunately I can't find a purple in Medium and that would be my first choice (although the hunt is on).
So grey or black?
Wondering about those earrings?
