I've been known to go and lock up hens in my PJs, come to that I've been known to let them out in my PJs too, with a fleece over it's just like 'odd leggings' really.. isn't it? Or I might be digging ragwort in heavy gloves with a halter top, shorts and fake crocs in the summer, that might be perceived as odd but again it's just normal to me. As is going to do some wee task I've remembered on my way to the car - like vaseline on a mare's udder outside my neighbour's kitchen window while wearing town clothes or fitflops, that kind of thing. Have turned up to work with hay in my hair many times!
Couple of years ago I had a neighbour wake me up to go catch a straying tup at about 10-1030pm, which I duly did in PJs and wellies, climbing a stone wall to get him and then bundling him through the fence and not sure how to get myself back as the wall was higher the far side! Scrambling about trying to get back up a too high wall in PJs and wellies when your fields lie along a main A road, when even at 10pm it was still reasonably light, might constitute eccentric I suppose..
