Physically the Olsen twins look fine, but that fact that they never smile makes them look older and grumpy and unhappy with life. That and the heavy eyeliner gives them almost a goth vibe. Do a Google image search, it's as if they haven't smiled once in the last decade. Also looks like they had botox or some kind of facial surgery.
They just need to stop with the surgeries and smile more like their sister.
Definitely not Mary Kate and Ashley, they kinda aged poorly. Jodie aged well and even though she was on drugs for a little while she got herself back on track and she looks great. I think Candice Cameron probably grew up the best, she stayed on the straight and narrow, has a nice family and she aged really nicely.
The Olsen twins had a brief moment in their late teens, around the time when New York Minute came out, when they would have blown the others away, but now they've got that Lindsay Lohan coke addict look going on.
I had such a crush on Candace lol. I didn't even know how she looked today, wow. All look good but Jodie looks the best I think. The most natural and healthy looking to me. Maybe it's just the makeup they're wearing?
I think they're all beautiful. They have all aged well. But I think it's MK & A attitudes that make them come last. Shame... I was such a fan of the Olsen twins growing up. Full house is still my favorite show.
