If you don’t have a lot of money in Paris – say you spent all your money just to get there, and there’s not much left for shopping – no worries! Window shopping is a very pleasurable pastime. You don't have to spend a centime.
Sometimes I get filled up just looking in shop windows or walking through markets, regardless of my interest, or lack thereof, in the products. The colors, design sense, the aesthetics of Paris can fill you to the point of saturation, even over-saturation. It’s all just so beautiful! After a while I can’t take it all in.
