Opt for single-breasted suits in dark colours. Get them tailored to the right length. Mostly, you’d need a bigger jacket to accommodate your belly which would result in longer arms and legs. Get your blazers and trousers tailored.
Look for heavy and stiff fabrics that don’t cling to your body. Go for ankle-length straight-fit trousers in neutral shades.
Opt for raglan-sleeved tees and shorts. Shorts will elongate your legs. Go for shorts with elastic which will give more room. Add leather boat shoes or sandals.
