I've never had a "nice" handbag - and am thinking of buying one because I need a new bag anyway - are designer handbags really worth it the price? Do they last longer?

I normally just buy bags from Target or Marshall's, but I use the same one until it falls apart. Do you actually have to take care of them in some way I don't know about?

I'm looking at a Dooney & Bourke Small Lexington Shopper if that helps, I need to go to a store and check it out though!

Probably stupid questions and I feel like I should know these answers by now as a woman in my 30s!
