Love everything about it!
Color: Brown
Absolutely love this bag! It’s real
Leather! It’s soft and slouchy. Has MANY inside pockets which like because I carry a little bit of everything. Has plenty of room without being overly huge. I’m using the crossbody strap to keep the weight off my shoulder and my hands free. This is a good handbag…and I am picky! This is the 4th bag (brand) I have gone thru this year alone. I’m gonna stick with this one (brand) til it wears out.

Color: Wine
Very beautiful, I only returned it because I like a much sifter leather, liked the crossbody and the deep burgundy color. Nice and big, how holds a lot. I would recommend this bag

Lightweight
Color: Black
I’m not crazy about the leather but I love how light it is and all the compartments. I got tired of heavy leather shoulder bags and so did my shoulders. It’s perfect for every day and very roomy. I’m using the shorter strap for ease.
I recommend this bag.
