As Harrods girl pointed out in her post A new way to layering, you should be getting a plain colored tee (round neckline please) and a camisole top or a dress to pair it with this spring.

Miu Miu showed it in its Spring 2006 Ready to wear collection, and the trend is starting to take on the streets.

Although I can't say I'm all for pairing dresses with tees because it looks a bit odd, as you can see on the picture, and dresses are much too pretty to be fooling around, I am all for showing your camisole top with a plain shirt.

I even found a great one to start with, a denim Miss Sixty camisole.

And, yes, people in Europe have been doing it for some time now. Not just the tee/camisole/corset combination, some do it with tee/spaghetti straps tee as well. It looks great!
