1 | Leave it to rest
Always rest your suit at least two days between wears. This will give fabric which has stretched in the knee, in the sleeve and elsewhere a chance to relax and return to its original position. It will also prevent wear on stress spots.
2 | The golden rule
Always ensure that the cuff of your jacket sits no lower than the base of your palm and no higher than your wrist bone. With your trousers a good rule of thumb is to ensure that the hem kisses the top of the shoe without a break.
3| Choose the right fabric
Ensure that you’re wearing the right fabric for the season. Linen and cotton in summer (even certain types of super high twist wool will work), and cashmere, tweed or merino in the winter. Sweat patches and shivering are both unsightly and avoidable.
4 | Get the length right
Always ensure that the skirt of your jacket fully covers your seat. Short jackets are not flattering on anyone, even the skinny. A full length jacket with a nip at the waist will look flattering on pretty much all frames. There’s a reason why this has been a rule for years.
5 | Know how much shirt sleeve to show
Make sure that your shirt sleeve peeks out no more than a centimetre from beneath the cuff of your jacket. Too much of a gap will make the sleeve of your jacket look too short.
