I do not have your typical skinny eyebrow, nor a uni, but they are slightly bigger then most girls. They just look like they have never been plucked. Do guys find natural eyebrows a turn off or would you find them attractive?
It's really not always about the thickness, I think her name is denise richards..i think, and she has thick lovely eyebrows, but the thing is, you want them to be groomed. Its more about if they have stray hairs and look really untaken care of, not if they are thin or bushy.
Fake-y eyebrows look dumb. I know guys that can attest to that. If you've got natural eyebrows and they look good, that's like, brownie points. It's always better if you look good naturally than if you try really hard to look good.
