Read the print from a distance
Stand far enough from the mirror to see the overall effect. A small repeated pattern may look almost like a texture, while a large motif remains very visible. Choose a top after seeing that difference rather than judging the print only close up.
Pick one colour already in the trousers for a simple connection. It need not be an exact match; a related shade can work. A neutral that you often wear may be more useful than buying a new top for one minor colour in the print.
Keep the first outfit simple
Try a plain shirt, fine knit or cotton top and familiar shoes. Check the waistband with the top tucked and untucked. Pattern does not remove the practical questions of fit, pocket shape and hem length.
If you enjoy mixing prints, introduce a small patterned accessory first. Look for a relationship in colour or scale, then decide whether you like the result. There is no need to make a bolder combination merely because the trousers are already patterned.
Check what the outer layer adds
A jacket may cover much of the top and leave the trousers as the main feature. A long coat creates a smaller strip of pattern below it. Put both on before deciding how many accessories the outfit needs.
Before buying printed trousers, picture two ordinary situations in which you would wear them. If every imagined outfit requires new shoes and a new top, they may be less versatile for your wardrobe than the print initially suggests.
