Your piece on a PJ party got me thinking. I've noticed pyjama tops worn as normal day shirts. Is it sloppy or a fashion thing?

Mr Dandy: It depends on who's wearing them (LOL)! I love that you still see grandpas in their PJs at the supermarket in certain neighbourhoods, but it's not exactly a great look. It's not a Hugh Hefner thing, either. In the designer world, this trend has been around for at least a couple of years, too. Starting in about 2009, brands such as Dolce & Gabbana began making fancy PJ-inspired daywear for girls, and it's continued to be pretty hot this season. Style icons such as Rachel Roy have been seen out in them. Why is it always the women who have all the fun, though? For guys, I've only got two designer picks. There's the Louis Vuitton cream and navy striped shirt, which was styled on the runway over another shirt, almost like a jacket (HK$14,700; The Landmark, Central, tel: 8100 1182). At Salvatore Ferragamo, there are a few great cotton shirts with PJ-inspired contrast piping in white and beige or white and blue (HK$3,800 to HK$4,500; IFC Mall, Central, tel: 2234 7388). Wear them untucked over jeans or casual trousers; blazer is optional.
