My Petit Noe is only stiff/rigid at the bottom, the body of the bag is soft and pliable.
My Alma and Monceau Epi are VERY stiff. I'm not very fond of the Alma in Epi - but the color makes it a keeper. One of the design features of the Monceau is that it's structured and she is elegant in Epi!
My Segur is my little black bag for occasions when I wear the little black dress attire, but she isn't stiff at all.
This is good to know. I thought long and hard about an Epi Alma before ultimately passing because the bag was so stiff (still think about the bag, though!). I also considered an Epi Neverful but again, the bag felt stiff and in that style, I wanted it to be pliable. If I knew it would soften, I might get one, Maybe I need to look at a Noe!
