Roomy, Quality and Versatile
Color: Navy
Very nice quality and appearance. Large enough for wallet, phone, etc. Easily converted from clutch to shoulder purse with removable chain. Handle trim and chain are gold color. Wish it silver but very pleased overall and feel it is a good value.

Beautiful clutch... but chain is defective
Color: Navy, Color: Navy
This is a really beautiful clutch and the size inside is perfect for your necessities. (lip balm, hand sanitizer, pocket tissues, husbands inhaler, hand cream) I really loved that about it however, the chain which is the only option to not holding it all night is terrible. I bought this clutch for a gala but the chain got stuck on my dress just the first time I tried it on. I wish there was another option so I don't have to hold it all night. The chain is really bad quality. It will shred my lace dress. Also the chain is super long. Like too long to actually wear on on side. Or it would fall off all the time. I am 5'9 and this chain to super long for me. You would have to wear it as a cross body- and that does not look nice with formal attire. Returning.
