It won't be fun if the a/c is on full blast freezing in a short sleeve t-shirt which is why I asked for other's experience! :
Agree with the other post, depends where you are. If you'll be sitting (and you tend to run cold) take a cardigan that you can easily take on or off. I'm an on the floor, jumping up and down kinda person --- plus there's the Paul hotness factor ops: so I'm in short sleeves or tanks and depending on the season I alternate between shorts/skirt or jeans
