A grey jacket with a patterned waistcoat places different surfaces beside each other. The jacket appears quieter while the waistcoat has a clearer line pattern. A white shirt and grey bow tie complete the upper combination, with one hand at the front. The picture ends above the complete trousers; shoes and hem are absent. It is therefore particularly useful for comparing layers rather than deciding the whole leg proportion.
If you enjoy the combination of quiet area and pattern, try it with real pieces. Leave the bow tie out first and look at jacket, waistcoat and shirt. Add your intended neck detail afterwards to identify which extra line you enjoy. Ask about the waistcoat back if you may remove the jacket later; its front does not establish identical design behind. Finally add the whole trousers and shoes before choosing a complete suit. The image idea may also help compare separate pieces you own. Check their actual colour and material relationship rather than assuming that a shared grey name makes them match.
