Heck yeah! You look fine. If you're really worried, throw a tri-top or fitted technical t in your bag and decide on the fly whether you really need it. I don't think you do, but sometimes jitters make us think otherwise.

I like your bike tan. I am just starting to get mine, and I realised I'm wearing a sleeveless top in a summer wedding in August, so I'm going to have to find some sleeveless bike jerseys and tops for running. If my chest and back are pasty, that can be dealt with, but my arms would be really obvious.

Denise, you look good in your pictures, I love your top!
