i've been hearing so much about sizing up on this particular pair - 887k. i like the wash but i just don't know what size to get. i really don't want to have saggy ass because it's big on the waist, and i sure don't want to not be able to pull them up if i got my usual size. i had this experience with thanaz 8880k. i got my usual size, and i felt like the blood circulation on my legs were being cut off when i wore them. i never even worn them out and had to sell them.
