Groves, context's measurements are pretty accurate. But since they changed it it, my 27's are the 28 measurements. Don't know if the vanity size changed our not .
27 PS with a month of wear. Tts is like 29
Waist aligned 15
thigh @ crotch 10.75
You might be able to get the waist to stretch. I wear a belt and dont want it to stretch much more. Hopefully those measurements can help you get your size
Their measurements are all wacked out.
Leg opening increases with size and then goes back down? Unless this is due to an increase in seam length from tagged 28 to 29.
