I haven't seen enough of the top one, but the bottom one is both sexy and classy and really suits you. You always were an attractive young woman who was classy and fun and that blue outfit reflects that.

Either i'd say :) they both look clubbing outfits to me, so which ever you prefer! you won't look out of place with either.. though i'd say 1st is slightly more clubbing style.
You look lovely by the way.
