Here are some tips on mixing patterns of scarves with tops.
When mixing a stripe (geometric) pattern with a scarf, look for a pattern that is either more sparse and non-geometric.
You can mix stylised prints with naturalised prints.
Animal prints are a dense print, so work better with a more sparse print on the scarf, but they are also a curved pattern so can work well with other curved patterns. Look for colours in the scarf that work well with the colours in the animal print.
Also consider wearing a print that is tonal/monochromatic (one colour) with a multicoloured patterned scarf, but the colours in the patterned top must be in the scarf.
