I have six LV bag's but my two favorite are speedy 25 epi black and speedy 25 monogram . Ive been used them very day since I bought them. They are definitively a very good choice. Very roomy for a little bag (a put inside my purse, my handy, my stock of make up and there is still room
If you like sober handbags but extra chic choose epi leather. It is such a wonderful leather. I have always a lot of compliments with my black epi speedy. If you like to show off a like bit more take a monogramm (multicolor or classic) but they are "weaker" , because of the beige part of the leather which can become dirty if you don't take a lot of care. However still a good choice!
Speedy is a very functionnal and modern model.
A SA has told me that is is the most popular LV bag in the world and I agree.
