I'm sorry to say, you are wrong on several counts. First, when I last checked with the Hong Kong Observatory, I saw that temperatures are forecast to flip-flop quite a bit more before true summer arrives. Second, and more importantly, I cannot condone the silliness of shorts suits. Either wear a suit, or wear shorts. Third, have you ever considered that you may already have one? Hint: hemming suit trousers would make them into shorts.
Ignore him. Now go take a look at the almost preppy blue cotton blazer with funky paisley lining (HK$10,399) and matching bermudas (HK$3,499) at Comme des Garçons (10 Ice House Street, Central, tel: 2869 5906). Slightly out there, but really cool, is the jacket (HK$3,290; Harvey Nichols, Pacific Place, Admiralty, tel: 3968 2668) and shorts (HK$1,790) from T by Alexander Wang in a bright blue sort of wetsuit material. Have more fun with Kris Van Assche's gingham check version: a caped hoodie/anorak (HK$13,020; Harvey Nichols) with pleated short-shorts (HK$4,590). Or get a wild print from a fabric shop in Western Market (Sheung Wan), then ask your tailor to make you something based on your favourite suit.
