We go to 2 these, one in a big city and one in a mid-size city. The big city one is more dressy/trendy. I (a women) personally wear black dress pants, my more comfortable black dress shoes (bc we are on our feet the entire time) and a nice dress shirt. Some people might wear trendy jeans with heals while others may wear a cocktail dress. Some men may wear suits & tie while others wear a sweater with kahkis. I just go for the in between bc that is what I am most comfortable in.
I am going to one next Friday and am looking forward to it! Hope you have fun at yours!
