Measure your neck circumference at the base where a collar would sit, and your sleeve length from the center of the back of your neck to your wrist with arm slightly bent. These two measurements define your dress shirt size.
European slim fit is cut closer to the body than American regular fit. If you normally wear a US Medium, you may need a Large in European slim-fit brands. Always check chest measurements.
US and UK pant sizes use waist measurement in inches (e.g., 32 means 32-inch waist). Inseam length is measured separately. EU sizes use a different numbering system that corresponds to these measurements.
For most categories, US and UK men\'s sizes are very similar or identical. The main exception is dress shoes, where UK sizes are typically 0.5-1 size smaller than US.
Athletic fit is designed for broader shoulders and a narrower waist. If you have a muscular build, athletic fit may drape better than regular fit without needing to size up.
