These might be the ones I bought but the listing looks different now. Different set of pictures. And different sizing. :-/ Anyway you have a choice. These ones don't have contrasting trim, which is actually my preference. I went for low-key black although the colours were tempting...

Received my, er, loincloth.
It fits (XL for my ~90cm waist) and feels the right size bit the flaps cover slightly less than I was expecting. A bit of lower cheek at the rear and the front flap wants to ride up above the pouch, or if I push the pouch to the side, ride up over me. Perhaps if there was more fabric to allow the fabric to still fall naturally despite the waistband stretching a little or perhaps if there was a little weight in the hem, these may be less of an issue. As it is, I'm not confident that wearing it shall prevent surprises on the part of approaching walkers...
