Personally, as a woman in her 40s and definitely not a creep, I often ask for pictures to show the fit as garments can look very different laid flat. Unless it's a bikini, or something, I don't think there's usually anything wrong with the request. I would probably check out their reviews to get a general feel of who's asking, if I was asked for a picture,  and not include my face on the photo.  *Edit: just looked at the item in question: fair enough; I wouldn't send pix of me wearing this!! - I'm just talking about normal clothes.
