Regarding* buying things in more than one colourway.
When I was much bigger than I am now (so huge) because I’m short the plus sizes that fitted were few and far between and absolutely nothing within 30 miles of home so when I found something which fitted I bought other colours because I was never convinced I would ever get something else to fit.
After shedding a lot of weight fitting wasn’t such a problem but it was ingrained in me and it took a long time to get out of the habit. Unfortunately I have put on a lot over lockdown and I can feel that feeling coming back with a vengeance.
