wow, the vote is pretty unanimous on the peony. i'm going to play devil's advocate: i vote carly! reason being is that i see the carly as a more classic piece. the peony is more of a seasonal or trend piece. i'm sure there are ladies who will say that the peony is not a trend piece and is the type of bag that you can wear every spring/summer! but to me, it's more of a trend.
coach always creates new styles every spring/summer and fall/winter. for example, remember when the scribble came out? it was so successful and i loved the colors! but then coach came out with the pastel scribble. and then coach had the scarf print...and then the straw totes and the white signature with bumble bees! aaah, i couldn't choose among them, they were all to beautiful!
but i don't see a lot of girls with those seasonal or trend bags anymore. i always see the signature wristlets, the signature demis, sohos, hobos, and other coach classics. every once in a while, i'll see the scribble. i'd hate to say this, but i feel that these trend pieces get outdated in about a year when coach launches new bags.
personally, i'd go with the carly because it's a more classic piece that can be worn any season, and any year. at least, that's my two cents.
let us know what you decide!
