I sold everything I had from LV. 3 T-shirts, 1 pair of shoes (in monogram denim) and one small messenger bag. I didn't wear any of those items, even though I liked them when I bought them. The LV monogram denim shoes didn't go with anything! They always looked bad.
I like that little pochette, from the picture it seems something that you could always use, but, again, I sold everything from LV for a reason... you can sell it easily, for a good price, so
if you don't use it and have something else in your mind, sell it.
