I need ideas for a spring/summer cardigan(s). Between the temperature swings courtesy of Mother Nature and the AC in every building in 100 degree weather, I never go anywhere without a cardigan. Usually I wear whatever cashmere wrap I've been using all winter, but this year, I already wore it to death and need a new one (or two or three). However, since I am usually wearing it at least once a day, it seems to take over my outfits. Should I buy all white T-shirts and a variety of cardigans? Or two neutral cardigans that can be worn differently? Or use large silk scarves?
