Various Möbius garments

I wear the Möbius belt!!! [tr]

Reminds me of the time when I was undergrad (doing joint computing/pure maths), and our geometry lecturer turned up wearing this most outlanding waistcoat, light blue with enormous lapels which reached right across the collar, and tapered all the way down to the bottom of the waistcoat. It was, we all agreed, a rather odd style statement for an otherwise extremely tweedy lecturer.

However, all became clear near the end of the lecture, when he explained that this particular garment had been lovingly crafted to order by his wife, and consisted of two Möbius strips stiched together in such a way as to create a garment with only one surface and only one edge. Yes indeed, the man was wearing a (very seventies) Möbius waistcoat.
