I am loving One Shoulder Dress. Because its looks always sexy for anywear. I would like to suggest you that you should go with One Shoulder Dress.
I think the first dress is gorgeous but I believe the second one is more elegant and it will give you the sexy but sophisticated look and both colors look amazing too.
Second dress seems nicer, although it really depends on which one suits you in the end. :P
Dress 1
I like the second one more especially in the black
