I have one of my dad's old white dress shirts. It's a little too worn to be the crisp white dress shirt he'd wear out, but it's just right for me. I can throw it on with a pair of dark wash jeans for a classic, easy look. It's the best "jacket" for summertime, looking great over tank tops and sundresses. My white shirt was a fashion savior after a recent sunburn by being soft enough not to scratch, light enough not to overheat, and protection enough to keep the sun from burning me any more.
I have a couple other men's dress shirts, mostly purchased second hand. They layer well over tees and under vests. Whether tucked in and billowy or loose and unbuttoned (my favorite) it's the shirt that can be worn a million ways. Jael Paris tried some unique styling several years ago, and we've even considered men's shirts as skirts.
What is your favorite way to wear a men's dress shirt?
