Upgrading essential silhouettes has been Chitose Abe’s career-long mission statement designing at <b><a href="http://www.selfridges.com/cat/sacai/" style="text-decoration: none"><font color="black">Sacai</font></a></b>. Combining menswear with womenswear, Abe chose to break down associations of socially prescribed uniforms by inflecting them with runway impact. Here she adopts the confines of a tracksuit sweatshirt, but spangles it with shimmering sequins, topping it with chiffon as fluttery trims around the sleeve seams and the hem.
