Born in Detroit, 45-year-old Parsons-educated Anna Sui never really wavers from her girly/punky/preppy/babydoll formula, but somehow, it always works. For spring 2010, Sui showed retro funky schoolgirl, with lots of plaid, zany '60s patterns and a healthy dose of fun.

The theme seemed to be circus, with a nod to Mary Quant. I'm not sold on the tights, but the dress is cute!

Styled in to a riot of color, this vest and dress would look great farther away from each other, no? Also: How cute is Chanel Iman?

The collection veered into shine, which was maybe not the best direction.

But a plaid shrunken blazer paired with matching walking shorts? Could go punk or prep, and looks pulled-together and fun.

I'm digging the little vests, and the blouses, even if I wouldn't wear them.

I wouldn't wear this either, but it made me smile.

That punchy blue blazer could just as easily be paired with dark denim jeans; the dress has a nod to the psychadelic '60s without looking dirty messy hippie.

A wee dress with a teeny tie and a bitty belt, because as a nation, we're scaling back, you know?

One thing this collection has is a sense of optimism: Although Anna Sui loves black and purple, she threw in a lot of other colors and played with patterns, making upbeat, fun clothes — and instructing the models to smile. The show feels light, happy, carefree.

And she also proves that spring clothes don't have to be bright yellow and green and white: This purple coat is fabulous.

This right here — black and purple dress, verging on babydoll — is classic Sui. The sandals, on the other hand…

I love all the '60s prints, and if I can't wear them, I want them as sheets.
