Beautiful and very well made
Color: B4/Merlot, Color: B4/Merlot
Simple but very beautiful bag. Very real leather and I love the little wallet specifically made for it. It matches perfectly to me. Not the Merlot color but the tan goes with the gold hardware. Also my iPhone 15 pro max fits with ease. This went on sale for $157 so I ran to checkout! Such a great deal, I’m happy.

Coach Mila Crossbody Bag-love it
Color: B4/Moonlight
The Coach Mila Crossbody Bag is stylish and well-made, with plenty of room for my essentials. I'm very happy with the quality and design! However, the color I received wasn't exactly what I expected. I'll be visiting the Coach Store to resolve the issue, but overall, it's a beautiful bag I'd recommend.
