Nasir Mazhar’s style as a designer is almost as much about physique as it is about clothing—since his very first collections, he's certainly had a type of model he prefers, and while his clothes change from season to season, the muscles stay the same. Today, Mazhar showed his latest for spring 2015 as part of London Collections: Men, and all in all, it might be his most refined collection yet; the fits are sharper, the fabrics subtler and the colors quieter. But no matter how sleek he might get, Mazhar's gun holsters, b-ball shorts and track suits will certainly look best after a little time at the gym.
