What is upscale attire for club?

Question

I am going to the club show and party in NY in next week and it calls for "Upscale Attire". What exactly does this mean for women? Should I wear cocktail dress?

Is there any chance for tight jeans or black pants with fancy sleeveless top?

Answer 1

I would think upscale attire means no jeans.  I think a hot dress with nice makeup, but casual hair would look good.
