I just cannot get my head round why people are purposefully making their eyebrows look like some budget werewolf costume. I've never been one for plucking my eyebrows but fuck me, this style literally looks Neanderthal. Like she needs a heavy brow and a club... they also look reminiscent of seventies snatch.
That's a 90's and early 2k trend... Most girls with thin or overly plucked eyebrows look rather skeletal even if they are fat or chubby faced... And they also look more significantly aged. (Old)
Thick eyebrows is what's "in" now, so more people will start to find girls with thicker eyebrows more attractive... Needless to say looks more natural.. And gives a younger appearance.. Natural is more beautiful...
I'm not a fan of the second look at all. It just looks like she hasn't maintained them for a long time, and kind of like men's eyebrows. I don't like the super thin look either, but the top look is pretty nice. Mine are just barely thicker than the top ones and I've been blessed in that department, because they have a natural shape to them like that, and barely require any maintenance. In fact, I didn't do anything to them until I was 18 and people were shocked when I said they were natural.
Either can work, it just depends on the individual. Eyebrows grow back so experiment and see what suits your own face best. I have naturally shapeless eyebrows that are on the bushy end... so I prefer a fuller look. Thin looks far too carved out on me.
