i am re-evaluating my comment. i was watching the season six part one of sex and the city last night (from great sexpectations to hop skip and a week). carrie wore what i would consider to be a very fancy sapphire necklace with a variety of outfits...including cargo capris and a cut off jersey.
yes i know it's tv, and i know it's carrie but this necklace was along the same line of fancy as these earrings....it looked fabulous! and not fabulous in a "couldn't pull it off in real life" way. so now, i like (and want!) the second ones.
I love the contrast of plain with fancy.
It makes the plain elements less boring and the fancy elements less OTT.
