I don't understand expensive bags but everyone has their own tastes.
I'd much rather buy an extremely adorable purse or make one (I make purses) for MUCH less moolah and have moolah left to spend rather than buy something with a huge price tag, plain jane looking and quite a few people have them. I don't buy anything designer... I'm a bargain girl and usually if it's for me and it isn't on sale, I don't buy it. Like, I wouldn't spend $20 on a tee or pajamas for myself but I will for my dog. Rather funny.
