I searched all over for "industry standard sizing for underwear" and found nothing. I also looked at European conversion and none were close. I have never in my life seen women's underwear sized as anything but XS - XL. I wear a dress size of US 4 and the smallest size offered for the panties is 5 - how can I go down a size?

My guess is that 5 = XS, 6 = S, 7 = M, 8 = L and 9 = XL but that is just a guess. I think it should be quite easily for the staff to provide some sort of conversion and that customers shouldn't have to figure it out on their own. I won't buy these until the sizes are given with some sort of familiar conversion. Please do so to make shopping on this site a bit easier.
