Black with flowers
Color: Black Flower
I purchased the black flowered version. Good size purse. I carry a lot of stuff and have plenty of room. I love the side pocket for my kindle. Seems to be well made I will revisit that at a later time as I am rough on purses. Stitching looks good. There was a smalls of the material that after leaving it sitting an unused room left. I think they could have left off the clutch bag and dropped the price a few dollars. Over all I am satisfied with my purchase.

Beautiful Quality Purse - Highly Recommend
So happy with this purchase and love the bag! It was packaged well and like a high priced item, in paper wrap and plastic & a box. It arrived in perfect condition. I was very surprised at the quality. The reviews were mixed but mostly good and I decided to give it a try. It is a beautiful dark navy, elegant & well made. I was proud to carry this at my nephews wedding. It has a chain option, which I didn't use this time, and has lots of room for many items without being overly large. I have one of the largest cell phones with a case and it fit perfectly. I actually didn't have enough items to fill the bag, LOL. My husband asked me to carry his things and still had plenty of room. It was perfect and I received compliments on it. After the wedding I wrapped the purse back up it it's original package and stored it away for my next event. Highly recommend this product and will purchase again for sure!
