Girls, Is it OK to compliment a girl's sports bra?

Turtle_Titan
Ok, so I was hanging out with friends and pointed out to one of them that she and I matched. She had on a sports bra under her tank top that was the exact same color as the shirt I was wearing. I didn't think it was a big deal since the straps were clearly visible on her shoulders, but she seemed to be really embarrassed about it and quit wearing tank tops for a week or two. I really don't want to make this mistake, again. Was I out of line: is this something that I shouldn't comment on or do most girls appreciate it when guys notice little things like this? Thoughts?
