Adidas by Stella McCartney is always one of the season’s hottest collaborations. Working together since 2005, the sportswear giant and British designer have even gone on to create the Team GB kits for the London 2012 Olympic & Paralympic Games. If this doesn’t whet your sartorial appetite, then there are, of course, the high-performance-meets-high-fashion collections that bridge the gap seamlessly between style and substance. Created with Adidas’s signature climalite® technology, slim-fitting racerback tanks and pale-hued camis promise to keep you cool and comfortable as you work out. Choose them with the label’s skinny leggings to keep you the source of envy both and in and out of the studio.
