Interesting! Topic of GUYLINER = guys + eyeliner on Lovelyish.
Personally, I don't mind it at all - as long as it's for the right guy. I even know a couple of guys at school who wear it sometimes and it really makes their eyes pop subtley. I find guys who have a bit of a prettiness or masculinity to them look even better with eyeliner. It just doesn't seem to work for "cute" ones. I can't seem to find a picture, but, for example, eyeliner on Jaejoong = YES. The same look for Junsu = NO. Since it's not common to wear eyeliner among the general male population, I think it shows confidence and thus ups their attractiveness. Would I date someone who wears eyeliner? Sure -- but I think that should be the extent of make-up use for guys... I'm not sure if I can handle it once they start wearing mascara, bronzer, blush, or gloss... but actually, I think concealer is fine too as long as it's not cakey.
Update on Fifi Lapin -- this is adorable!!
So girly I love it.
