Hi, What is the style of the bbag that Nikki (the black bag), Demi (the purple bag), & Christina (the white bag) holding? They look so lovely. I am now debating between that style & the twiggy. Does Twiggy hold its shape if you don't put much in there?? Which is a better style out of those two? Planning to get a pink or the rouille. It's so hard to pick a bbag as I love all of the colors & styles. Wish I'm a millionaire Thanks.
