Must Have?

I'm dying because Monday at the Pumpkin Patch Play Day one of the moms had this Tory Burch diaper bag that I didn't even know existed. I am so jealous and I've got to have it right now. I'm still using my old Kate Spade Messenger diaper bag from when Mary Slayden was born and its so beat up and grubby. Claudia is six months old now, so I'm wondering if I even need to spend the money on a new diaper bag. With Mary Slayden I carried it till she was over two though. I'm so fat and frumpy these days that at least I would look somewhat posh with such a stylish diaper bag.
