Hi Tooomz, nice to see you in the BV forum.
I just tried both colors in the maxi last Sunday, I have to say that the Orchid is too loud in the maxi, but very cute in smaller bags such as the medium belly veneta.
However I don't think the BV black is too plain, it's very classic with the gold zippers.
It also ages well, it will get some scuff on both corners but still looks fabulous. You wouldn't notice the scuff that much.
My Mom owns both black and ebano BV venetas, they're holding up pretty well in my opinion.
I think you can go for a black BV or the new 2010 grey, both are stunning!!
Good luck!! Do post pics when you decided to buy one!!
