I've had moments of yay each time I was able to fit into the old clothes in my closet that didn't fit anymore. This week I took out my favorite pair of jeans from high school (during my restricting phase no less) and they were perfect.
I was also happy when my waist dropped below 40 and 35 inches, which are considered cutoffs for disease risk for men and women respectively, at least in the US.
I didn't start taking measurements religiously (once a month) until pretty far into my weight loss, but I ordered an eShakti dress for a wedding in 2018 at about 30 pounds below my highest weight and my measurements were 61-57-70 (chest-waist-hips). The day before surgery, my waist was 46 inches and hips 57 inches.
My last measurements, from about a week ago, were 38.5-32.5-39.5. I've lost 30 inches from my hips, 24 from my waist, and 22 from my chest. (Yes, my WHR actually increased, but I've also been taking low dose testosterone for about 2 years.)
Things have started to plateau, but I still have a sundress that I want to be able to fit into and I imagine I'll get there.
