My initial thought is that you look around 30- there is a maturity about your face that made me think 30- although in reading your profile I can see that I am way off. Weightwise, it is a little hard to gauge with only a headshot, but my guess is 160's. Whatever the answers- you look good girl!!! =]
And you're 25. It's the light, and ya look tired. :)
I'm gonna say about 28 and 155-165. Am i close?
low to mid twenties, and healthy :)
