There have been some occasions where I have had to choose which YLF "rule" I will not follow, Usually on holiday when I have not packed wisely!
Here a few examples.
* I chose to wear a dirty sweater over wearing a denim jacket with jeans (or I suppose, over wearing no top layer at all and being very cold)
* I chose wearing shabby sandals overwearing better heels so as not to breach PPL
* I have worn long camis with jeans and T-shirts with skirts because they were the best option I had for PTL and wanted something fitter
Over to you!
