I would like to purchase the Sasha harness on Monday but the size chart is confusing to me. Under the review that Beck did someone from Spareparts commented that depending on the body shape the sizing should be ordered up or down. Something about full, half and quarter moons. Can someone help me figure this all out?

My hips are about 32" an inch below my hip bone, the fullest part of my hips are 35". I wear a size 2. less
