I did something similar for something similar

I doubt my ex T ever considered me a perfectionist, but for different reasons I think he read way too much in to the clothes I wore. I quickly developed a 'uniform' that i stuck to for .... I dont know - a year or so I think. A lot of the clothes I wore were centred on practicality- I really hated that he read **** in to clothes I wore because my skin was sensitive, I was bloated, had my period, had sore boobs, wanted to feel comfy on a long walk etc etc. I used to turn sessions in to a right big outing with long hard walks included - so a lot of what I wore was to deal with that. My uniform allowed me the comfort I needed without giving him the opportunity to read too much in to it.
I also always carried water with me on the long walk days, but I would hope he would have the sense to understand that was a necessity on those days and not read anything in to that!
