First off, I love them just as much in person as I did on my screen. Actually, I love them even more, because I get to put them on my body and I can't do that with a picture on the internet. In order to combine both worlds: here is a picture of them on my body on the internet:
She got them for me in ultra pale, which, hey, is pretty much my natural color, whodathunk it? The pair she got for herself is the same shade, and way too white from her California legs, but she expects to get back to that level of paleness during our Wisconsin winter. They're packaged as L/XL, and I'd say they're true to size (I wear a 14/16, for reference). They were pretty tight all-around the first time I put them on, but they're definitely a comfortable size now. As you can see, the "tattoo" stretches along the entire length of my calf, which I definitely appreciate.
They also just happen to be the same pattern as a pair of heels I have long coveted:

Ahh, to wear them together...one of my dearest dreams. Overall, I would give the tattoo socks a resounding YEA! if I was part of the Continental Congress and we were debating tattoo socks. In any other situation, I say: they rock!
