I want to buy my sister a pochette. She has a Speedy 30 and a Trouville. I was thinking she could use a smaller cuter bag for evenings, so accessories pochette came to mind. I can't figure out which to buy her though...mono, damier, of azur damier. I don't know if she'd like the epi or not. What do you think would be best for an evening bag or "going out" bag? Mono, Damier, or Azur? She is 33.
