Fashion and society had requirements of under garments and set rules for its use and purpose. I have read several articles and a journal of the time on the matter. It was suggested to have all the things needed to dress comfortably for some time before heading to the wedding. Several dressing gowns and several chemise and several bloomers. Fortunately, we don't have to talk about corsets and bustles! As we see in the Masterpiece Classics, every woman sat in gowns in white. Apparently, it was considered selfish of a young lady to have many white under garments as white needed frequent laundering at a high cost. I see sense in the writings of that time.
Choose style by comfort, not fashion. With four sons the debate on jockey shorts, boxers and the long legged briefs rages on. Go for comfort, guys, and durability. Colors should be subdued. White will virtually glow in the dark on a full moon! Buy a mom's idea of a year's supply and store the sewing repair kit and several yards of waistband elastic available from Jo-Ann etc. AND rotate!
