Lot like those Little Mermaid Ariel's...
...clamshells.

Sneakers, like...
...many Adidas and Nike and Reebok and Asics products are not classified as fashion in many design books.
Their technology has changed more than their looks.

How about...
...fashion designers that have dabbled in furniture design?
Jean-Paul Gaultier did a few items for Via... http://www.tribu-design.com/collections/alpha.php?ac=f&pict=3&lg=en&st=9...
Rei Kawakubo designed a whole slew of stuff for Pallucco... http://www.architonic.com/mus/gal/4104184http://www.gallery33llc.com/itemdetails.php?id=223629

oh, man
When I was in first grade (way, way back in 1961), my Aunt Gladys gave me a cotton knit pullover for Christmas. It had pretty much that same Mondrianesque color block pattern as those YSL dresses. Same colors.

And BOB MACKIE...his furniture just hit the market...CHARLES JAMES did sofas and interiors...

I'm sure we all know about Pierre Cardin and Paco Rabanne
One of Cardin's furniture designers was none other than Maria Pergay.
The first is a Cardin Desk, the others are pieces by Rabanne.

And also, not really a fashion designer designing furniture...
but rather a fashion house hiring a furniture designer, these iconic pieces by Jacques Adnet for Hermes.

..
Or was it Adnet using Hermes leather...Cardin did a few good-ish pieces but TOO much crap ola...love the table you posted...

OK, I will not comment Mai Shiranui's costume, but...
...her hairpin is great.

Adding to the list, I just read Pierre Cardin helped design a netbook.

And let's not forget that...
...sometimes fashion inspires design. Like this Carlton Ware's Denim Ware from 1970's(the era of unisex fashion).
