This one-piece is from women's workwear brand SUK Workwear in Australia. They make this in long torso and short torso. The sizing guide says that unless someone is very tall or knows they have a long torso, they should purchase the short torso. With the garment laying flat, I measure the pit-to-pit at 20", the waist at 18" and the seat at 23". The front rise (from the middle of the neck to the crotch, is 31". In case the numbers don't tell you, this is a very generous size 12 that will also work for a size 14.
