Buy this gold clutch purse rated a 5
Color: Gold
Gold clutch purse with chain strap. Absolutely beautiful! I’ll get a photo and come back to update. It looks and feels like a quality purse. Buy this purse. Rated a 5! Love it. Update: the smell the reviewers are talking about is the new smell. I did try the gold chain and once you snap it on the purse doesn’t close so I’m not using it and I’m okay with that.

Images don’t do justice to this beautiful bag IRL
Javier’s wife. This handbag is absolutely stunning! It is beautiful, the definition of classy and elegance for a clutch. Not your regular only one wedding wear cheap looking and common sparkle clutch. (that you find at mall stores). This bag is for a fine lady., is not your daughter’s purse. It is very well made with attention to details inside and out. Good materials. It looks like cream leather with silver handle piece. The size is wonderful too. It is just right. It isn’t small but still a hand bag. It is very elegant. It pairs amazingly well with my pale pink maid of honor wedding dress, because the cream color of the bag seems to have a faint pinkish undertone that is very beautiful, hardly noticeable, but when next to the pink fabric of the dress it shows more and looks very stylish. It would look spot on also with black and white business casual attire, cocktail dinner parties. That cream, silver combination looks well almost with anything and will dress up almost every outfit from simple to elegantly stunning. I will add pictures later. I just received it today. I am in love with this bag. 5 stars 100%.
