One connection is enough to begin
Choose two patterns sharing a colour. Every shade need not match. A recurring colour can connect the pieces while their motifs remain different.
Large and small in conversation
Try a smaller pattern beside a larger one. Two dense surfaces of nearly equal scale may compete; a change of scale gives the eye more room. This is a starting point rather than a prohibition. A deliberate collision can be interesting too.
Give a third piece a plain surface if you want a quieter result. A solid-colour coat can frame the patterns and allow them to play within it.
Look from farther away
Step back from the mirror. When the motif’s details disappear, which larger shapes remain? An outfit has a composition at that distance too. The V&A’s Art Deco feature offers visual references for the relationship between geometry and decoration; today’s pairings are yours to decide.
