Measure hips across the bone., measure waist across the biggest part near the navel.
Measure thighs, forearms and biceps at the biggest part. Measure wrist between the base of the thumb and that little, bony, sticky-out bit.
Hope this helps.
Also, I was going to post a congrats on the check-in thread at your 23lb loss. That's really good going and I'm glad you're not put off by a bad week.
