Men's Slim Waistcoat - To boost confidence and dapperness, add a waistcoat. For extra style points, nothing takes a suit from smart to smashing like a well-fitted waistcoat. Not only does it refine your look and fill the space between your jacket and trousers, it also slims your waistline and keeps your shirt tucked in and tidy. To choose the perfect waistcoat, make sure it matches your trousers and contrasts your shirt. Double breasted waistcoats tend to be a little warmer, so they're perfect for the festive season or if you want to ditch the jacket altogether, while the single-breasted variety tends to be more slimming. Either way, a well-tailored waistcoat is guaranteed to give you some added confidence. - Style: Waistcoat - Design: Plain - Fabric: Polyester - Sleeve Length: Sleeveless Details & Care: 74% Polyester, 24% Viscose, 2% Elastane.
