^She HAS aged. It happens, you know. But I think she looks mature in a good way. Kind of like how Ann Markley grew up and became a model. She doesn't look like she's trying to cling to her lost youth, and that's a good thing.
I completely concur with LadyDay. Models can't stay young forever. Yoanna just turned 30 so she's going to sign some signs of aging. The older supermodels we see in the high end publications? They're airbrushed to high heaven just like all the girls.
