I just gave my 21 year old son a "custom" shirt from Lands' End in a beautiful rasberry stripe/color with a button down collar. He loves it, and I told him under NO circumstances was he to EVER wear it with the button down collar un-buttoned. He laughed and agreed, but I'm wondering . . . Am I simply showing my age, and don't realize that he and his 19 year old brother are right - that you can wear button down collars unbuttoned at times? I don't mean with a tie and blazer, but they tend to unbutton them when they wear one alone, or even more likely with jeans and a sweater with the tail hanging out the bottom and the collar OUTSIDE the sweater (unbuttoned). That latter look in particular reminds me of a bad '70's look. Could some of you (especially the younger members) weigh in on this? Thanks!
