hey marly,
ok, since you already decided against I shouldn't be saying this BUT i will anyway... haha
I honestly think that every gal should have one fabulous evening bag that she can pull out for all the big events and always look chic. so if you think this is that bag for you, why not? if it is a trade-off btw day and evening bag, of course i'd say go for day bag, but if you have what you want, and you can afford it, i'd say it is good to have a nice evening bag. bv no less!
