Of course. This is why luxury brands exist. But I'd like to think that handbags and ukuleles are different. That's my naiveity probably!
YSL scribbled all over a hand bag to me seems the height of absurdity. But many disagree. I personally feel that the idea of "prestige" is counter to a happy life as one's self worth becomes tied to other's peceptions of them, and what they own, but if that is what some people need to get through the day, cool. I would, however, definitely spend more on coffee in a plave with a nice ambience. It makes my experience better. I love cozy coffee shops.
