One good piece of advice I can offer, is if you are selling clothing, always give full measurements. That is, it's not sufficient to just describe items as small, medium and large, as all stores / Brands have different sizings.
Give full measurements , what is applicable, waist, inside leg, chest, length of item, even lay a tape measure alongside these salient points in your photos.
Less chance then of having a disgruntled buyer and having the item sent back because it doesn't fit, or worse not as described, then you'd have to fully refund.
