Hi, I recently purchased two contrast collar Canali dress shirts (light blue and lavender). They each have a white collar, but the cuffs match the shirt color. Some fashion advice sites say that any contrast collar must match the cuffs AND be french cuffs. However, the shirts I purchased are button cuffs. Am I committing a faux pas by wearing these with a suit? Today's slimmer cut suits don't really accomodate french cuff shirts, so these shirts will fit. Perhaps they would work better with a navy blazer, with or without tie? Thanks.
