When it comes to getting the perfect fit for your new trousers, the Slater Menswear trouser size guide is a detailed and helpful way to check you're ordering the perfect size for you. We offer free alterations on all our suits but with the help of this men's trouser size guide, we're hopeful you'll be able to order the ideal pair of trousers for you first time. All of our suit trousers are 6" smaller around the waist than the size of the jacket.
