I would appreciate some advice from you all on what style I should buy for a black bbag. I must force myself to buy one since I have a lot of bright colors now! I have 1 city, 3 Twiggy bags, and 1 day bag currently. I really LOVE the twiggy the best, it is the most comfortable to carry for me, handles over my shoulder. Should I get a black twiggy, Part Time, or venture into the land of the First bag? Thanks!
