Personally I would go for the Pochette Métis but based on your thread I am afraid it might not be the best option for you since you find it a little bit bulky when worn…
Second option would be the Multi Pochette which is a bag I love and being eyeing for a while… is it a trendy bag? Yes
will it eventually go out of stile? Maybe… but so do many other bags..
I think it’s such a versatile bag that give you an array of options since the pieces can be used in different ways. On the other hand I would not get the Prada re-edition in nylon.
