My Grandmother had several hundred of these buttons rattling around in her button box. She used to do laudry for the Amy Aircorps and probably she and her family wore a pair from time to time back in the day. To say the least, she collected a few over the years. There is quite an interesting history on undergarments and I found a fascinating site here on the history of skivvies. It's a good read with great photos. I also found an interesting and odd vintage photograph online of three men working in their underwear. So there you have it folks!
Tifff will receive this beaded bracelett and matching stitch markers so she'll be knitting in style.--------
