Definitely hate this...adds up quickly.
I did a little post Christmas wardrobe refresh for myself, online, and only because more and more our stores are closing, our malls are dead etc, so I don't have that option anymore to go and try on, that I had only 4 years ago. 
Macy's gone. H&M gone. Loft gone. Limited/Express, gone. Mall DEAD and dangerous.
So between a QVC LG item that didn't work out, and a "Natural Life" dress that didn't work, and a pair of H&M jeans that I should have read reviews on first because almost everyone said size up, (not sure what that return will cost yet, haven't checked..)...but the first two...$18.00 to return 2 items! Target item is free return, I believe...BUT...I STILL don't have petite yoga pants that fit right!
I'm NOT doing this anymore. It's such a gamble to try to fit clothes online and way too expensive and a pain to pack up and return back and forth (I know, I know...some people prefer this to the "pain" of shopping around.) I'm going to have to figure out what brick and mortar I can still shop at for some things I've been wanting in my wardrobe. At 5'1.5", I truly am sick of trying online to figure if dresses are "petite" enough (most stores don't have an actual petite line), trying to find pants that aren't 6 inches too long etc, and then paying to return.
Amazon is great and easy that way, but a lot of the clothing is cheap. Still...there are some name brands there...I'm going to look more there, for now.
