Thanks ladies for the suggestions. Very helpful. I've sorta deal with this when going to Orlando but usually I can deal with short sleeves there. (after shoving the sweater into my carry on) I was worried about how hot I would be once landing in Vegas and how to make sure I was dressed appropriately. As far as the back flab on my arms, I'm trying to convince myself I won't know anyone so don't need to be embarrassed when the stanard is Britney Spears LOL.
