Feeling nervous about pulling it off yourself? Try balancing the scales of your patterns (e.g., large pattern with a small pattern, stripe with a floral, etc.) or keeping to a common colour palette (e.g., navy stripe with a navy polka-dot). Stripes can go with pretty much anything, although you want to be extra careful if you pair them with a plaid. As for leopard print, I may be biased, but I think it's the most versatile of the bunch!
