If you've been following my posts in this thread I hope you've enjoyed them, they're all 100% true but so far I've only talked about women I've seen through bedroom windows. I need to talk briefly about frosted bathroom windows as well.
With the modern trend for extremely bright lighting in bathrooms, 5 of the 7 local women I've voyeured, I've also seen them topless through their frosted bathroom windows as well. And I haven't even mentioned the 4/5 OTHER women in nearby houses I've seen topless in the same situation.
I don't know if it's deliberate or not but frosted glass doesn't really hide that much, especially if you're looking from a distance like through my telescope. Nipples are obscured but you can usually see the exact size & shape of bare boobs if a woman is standing in side-profile in front of her bathroom window with the bright light behind her.
Try it sometime if you can see bathroom windows from your place, you'll be pleasantly surprised how much detail you can see
