i think on some eyes colored lenses luk really nice and natural..it all depends on the eye shape and size i guess. i wore grey color lenses on my shadi and walima and i dun think it looked v unnatural... infact ive noticed my eyes look fuller and bigger when i have them on. some ppl i know, their eyes become narrow when they wear lenses... so its frm person to person. but i definitely feel only greys and brown, hazel shud b used for wedding.. the other blue, greens can look horrendous!
