Does this look weird?

Ok, so im having my graduation party in a couple of months. I wasn't sure what to weir so i asked my friends. Some of them told me to go formal, while others told me to go casual. So i combined those 2 ideas and came up with this...a really short dress, with black skinny jeans underneath ( i don't like showing my legs) and black high heels. Honestly, would that look weird?
