Instead, I'll pass on a piece of classic dressing wisdom from a well-put-together lady: "boring clothes" are totally fine; she likes her "boring clothes", but she gives them more character (and more usefulness) with accessories. Which sounds at first, I don't know, a bit old, like you have to have five sets of matching shoes and belts and earrings and purses to dress up your Little Whatever Dress. Like a teen doll that comes with "accessories."
But that isn't the case.
I bought a plain navy t-shirt at the thrift store, and wore it yesterday with a special silk scarf that also came from the thrift store. I dug through my jewelry and found a pair of blue bead earrings that Lydia made for me during her earring-making blitz a couple of years ago.
Here's another scarf-plus-dark-t-shirt. I was experimenting with the same scarf knot, so the only thing that's different is the scarf itself.
What does this have to do with "tiny?"
For the travel expert above, using accessories means that she can pack fewer clothes but still look good. Even if you and your clothes stay at home, a few extra extras might mean that you need one sweater instead of three, or that you can wear the same dress on more than one fancy occasion. You can wear a forgettable-colour top with a more interesting scarf or necklace. Which translates to less money spent, less clothing produced and wasted, maybe less closet space needed. Or, for some people, it means the option to buy the sweater or dress from a socially-or-ecologically-responsible company that they like but wouldn't otherwise have been able to afford. Or to buy very good yarn and knit the sweater themselves. As it says on the Project 333 home page, thinking smaller isn't meant to be a project in suffering; it's more like an opportunity for choice.
