Oh, you mean the denim trend from last summer? Both, but it depends on the effect you desire. Start with the cult, New York-based selvedge denim brand 3x1. Leap right in with its bestselling WM3 cropped, straight-leg jeans with a dramatic four inches of frayed fringe at the hem (HK$2,294; www.3x1.us). It's worth pointing out, however, that they are only available in black right now, and you'll have to put your name on the waiting list for the "light vintage blue" or white versions. Alternatively, there's the W2 mid-rise, skinny, cropped jeans with an evenly frayed hem in light, medium or dark washed indigo denim (HK$1,749). Another brand doing fraying is Acne Studios, which has light-blue boyfriend jeans with stringy hems (HK$2,699; 10 Ice House Street, Central). For something a little bit different, look to London's Marques Almeida, which offers a whole line of fabulous, frayed denim pieces this season. You might like its wide-leg jeans cropped to just below the knee, frayed just at the hem in washed-out blue denim (HK$2,999; I.T, 10 Ice House Street) or sparkly, metallic black denim (HK$4,199). Other brands playing with fringes on denim include Paige Denim, MSGM, Roberto Cavalli and House of Holland. To fray at home, simply cut to desired length and distress the edges with a nail file or even a food grater. Then, let the washing machine do the unravelling.
