Going to an art show tonight... I would normally not even hesitate and put together a nice dress and heels outfit... don't know what to do after my friend informed me she was going in jeans and a t-shirt cause that's her comfort zone and the best she can do is to not have writing on her shirt....I feel like she broougt this to me cause she knows my nature and just wanted me to know she was not going to dress up...She is my oldest friend, since I was in my early 20's...

What is a happy medium where I can go to such an event with two friends who will most likely being wearing jeans? My first instinct is to grab my trouser jeans , a sweater and booties... Does this sound like a good idea?
