A lovely and inexpensive touch for formal events.
Color: Navy Blue
Beautiful navy blue color, and well made! Nice to be able to carry it over the shoulder or by hand, with the strap tucked inside the bag.

Not Too Big or Too Small; Perfect Size
First of all, the picture shown on Amazon does not do this purse justice. The colour is beautiful and it pops. I love the design of this purse as it is not too big and not too small; it's is just the perfect size for any occasion. The styling of the outer layer is just perfect and not too over the top. Normally, when purses have rhinestones on them, it often gives off a rough feel but not this purse so no need to worry about that. Lastly and my favourite part is the small pocket that is inside. I'm a girl who loves to bring her ID and debit cards wherever she goes plus her little cash so that small pocket will be perfect to store these. This is definitely worth it.

Cute bag, cheap chain
Color: Stain Navy Blue1
Very cute, very spacious. I was able to keep my phone and a mini sewing kit with me but the chain broke 10 minutes into the reception while standing in line for the buffet. The whole point in buying this was so I could keep my stuff with me and not risk putting it on a table to the side of the dance floor after dinner. The bag itself is cute and I can get a replacement chain but it's unfortunate that I have to spend more money to make it work.
