Can I wear a suit jacket with jeans or will I look half-dressed and half-arsed? Mr Dapper: I'd never do it, there is too much risk of looking like an investment banker improvising 'business casual' on a work trip. Traditionalists would favour a sports coat or a blazer with jeans. However, Mr Dandy tells me that some of today's greatest fashion designers have recently advocated the look. Mr Dandy: And I love it, especially the beautiful, tailored jackets that look like the top half of a suit but are sold as single items, in pinstripe or check, and sometimes with a quirky element. You'll find everything from straightforward styles (HK$8,200; Comme des Gar?ons, 10 Ice House Street, Central, tel: 2869 5906), to funked-up details such as frayed cuffs or painted circles (HK$13,900 and up; Joyce, 16 Queen's Road Central, tel: 2810 1120). Mr Dapper: But whatever you do, please only wear it with very new, very dark jeans, or an old pair that has been broken in by you rather than by a designer. Skip the lace-up brogues (people will ask what happened to your suit trousers) or trainers (all wrong) and stick to loafers, please. My girlfriend keeps telling me I need to use some of those fiendishly expensive creams, like La Mer and Le Prairie, now that I am over 35 instead of, well, nothing? Is she on the money or just looking to steal anything I buy? Mr Dandy: Just use hers, then. Don't be sucked in by marketing just because you fear appearing feminine. Skin is skin regardless of x and y chromosomes, even for alpha males, so start taking care of yours immediately. Mr Dapper: I spend just as much on lotions and potions as most women do and that means: HK$1,200 to HK$2,100 for La Mer's famous Cr?me de la Mer (Lane Crawford stores, tel: 2118 7777); and HK$1,430 for La Prairie's Cellular Radiance cream or HK$3,350 for their Skin Caviar Luxe Cream (Harbour City, Tsim Sha Tsui, tel: 2895 9672). Try out Sjal, Rodial and Dermalogica as well, to see what works for your specific needs. If cost is an issue, consider the popular, no-nonsense Ultra Facial Moisturiser by Kiehl's (HK$140 to HK$220; Harbour City, tel: 2376 2921). For what it's worth, your trust issues seem to be far more pressing than your grooming regimen. I'm tired of wearing a white shirt and black bow-tie for formal events but I don't want one of those nasty coloured cummerbund and tie sets - what are my options for a chic and original formal look? Mr Dapper: Never ever wear the coloured-combo set unless you're at a wedding and the bride has poor taste. When it comes to an evening suit, classic is the way to go. Get yours custom-tailored in a timeless style using the highest-quality fabric you can afford. There is absolutely nothing wrong with a beautiful black tie or a more formal white tie, which is astonishingly easy to knot. Get yours at a store like Thomas Pink (HK$525 in traditional or thinner width for a more contemporary look; Pacific Place, Admiralty, tel: 2155 9021); or browse the men's section at stores such as Seibu (Yves Saint Laurent, Giorgio Armani, Cerruti, Boss and more for HK$790 to HK$2,900; Pacific Place, tel: 2971 3838). Alternatively, you could have one custom-made by Tom Ford or Brioni (Lane Crawford, IFC Mall, Central, tel: 2118 7777). Mr Dandy: And don't you dare even look at a clip-on or ready-made one. We'd also avoid replacing it with a long tie from Prada (HK$1,400 and up; Pacific Place, tel: 2918 9233). The long black tie was new and interesting when Tom Ford did it a few years ago but it's just boring now that every Hollywood actor hits the red carpet in one. (Reference: the 2010 Oscars.) If you really want to mix it up, then be inspired by Lanvin's Alber Elbaz. No, we mean an untrimmed piece of beautiful grosgrain ribbon tied around your neck rather than the cartoonishly oversized, colourful bow-ties in store now (HK$1,500; Lanvin, Pacific Place, tel: 2523 9512). We're so open-minded, we'll even allow you to skip the cummerbund.
