I like the shape, and I'm rather small so I think the size is a little more suitable (haha.. little.. boo). Don't worry though, I like both, and I'll eventually get the batignolles vertical, I just chose the Popincourt first !
I like both, personally. The Popincourt Haut came out first, had a different shape/style than other mono bags and you can't help but love the gold balls. It's still smaller than the Batignolles, but bigger than say, the loopings. So it's the perfect size for a shoulder bag without looking like you've stuffed it.
I plan to order the Popincourt Haut because I love the shape, the size (not too big, not too small), the brass details and the zipper closure. For that much money, I want a zipper. I love the shape of the Batignolles, but I just wouldn't feel that secure with that closure. Plus, I still haven't seen anyone carrying a Popincourt Haut; people I see usually carry a Speedy, a Cabas Piano or a Looping bag. I wanted something a little different.
I'm not sure if you mean the popincourt (which is a short handle purse) or the popincourt haut (shoulder bag). I personally love the popincourt. I have one and love the unique shape. The popincourt haut is very pretty as well. Unfortunately, people love it where I come from so I see at least 2-3 every few days it seems. That turns me off. I hardly see the batignolles...
