I'm beginning to think that lots of these body/sling thongs for men are made for taller guys. I ordered the smallest size and yet the front sags a bit and the rear rides up a little high. This is certainly not the fault of Under_Yours, with whom I've had the pleasure of dealing for a short time so far. There really should be an XS or XXS option for those of us that are either altitudinally (vertically) challenged or just simply want a tighter fit. It looks great on the model, but not so great on me, and I'm in tremendous shape for my age (Instagram @sbchnt and @1SexyThonger).
