To keep or not to keep, that's the question..

I did some shopping the other day and two of the things that I got are these from H&M, but I think I'm gonna return them. Don't really known when to use the skirt, and how to use the top.. It's a shame because I like both of them! But I can't keep them just because they're pretty, such a waste of money.

Haha sorry for looking awful! I mean come on, it looks like I haven't slept for days.

No, I'm not missing a hand, it's there, it just fell out of the picture. Looks really weird though..
