A regular crew neck t-shirt just looks awful on me. Now I know I won't be able to wear the camisole tops on their own, but I was wondering would I get away with them for work so long as I wear a jacket or shirt over the top?

I've been wondering about the aircon situation over there. I know it gets stupidly hot during the summer, but when you're indoors where there's aircon, is everyone wearing jackets? Does the aircon make it really cool indoors? Or do people just wear t-shirts indoors?

If I wore a camisole top (to avoid the crew neck line, which does nothing for me), with a jacket on top, would I be absolutely sweltering indoors during the summer? Or would I be comfortable, taking the aircon into account?
