>> Stella McCartney likes to drop hints about her cruise collections — or "Spring" collections, as she calls them — by debuting them on celebrities in the weeks before the fashion press sees them.  She inaugurated the idea last year with Madonna, and this year gave Cameron Diaz a white dress with black floral beading from the Spring 2010 collection, which just debuted today, to wear Friday night.

But perhaps we should watch what Stella herself wears the most for clues about her upcoming collections — the black lace jumpsuit she wore to the Costume Institute Gala May 4, which she made in the hours right before the event, is included in the Spring 2009 collection, as is the embroidered floral dress she wore to the Royal Academy Summer Exhibition Opening on June 3 and the white playsuit she wore to the New Contemporary Art Center June 4.
