What do you wear to a concert with business associates?

I have learned a lot of things in life and while studying business in school...how to dress for the interview, how to greet others, the various degrees of hand shakes and what they mean about the person you are meeting, how to eat, sit, hold conversation, dress for black tie and all.

Will someone tell me for the love of pete; how the heck do you dress for a Beyonce concert when attending with business associates???!!!!

This is a whole new playing field for me! Business calls for great shoes (usually as a woman I wear heels to boost my height otherwise the male business associates tend to ignore your input-honestly that is my experience) but for a concert at a major venue with walking and such....are sneakers okay? wedge sneakers? jeans? skirt? dress? It's evening so I know have the "Green light" to go glam but this is still a business sanctioned event...oh did I mention it will only be 35 degrees outside?

I came up with 2 starters but I don't know if it is appropriate:

1. Green skinny jeans and a navy boyfriend blazer with white blouse

2. Blue tuxedo tapered pants with either a flowing black vest and black shirt or black blazer (gotta find one)

each with black wedge boots or black platform heels and just hope that the car will pick us up and drop us off in a good location so we don't have to walk much.

I don't know many of the details yet but I am guessing everything will run smooth as the company sponsoring the event owns the venue.

I will take your suggestions. Keep what I have or look for something new?
