What a bad experience in winter. If the thigh high socks become transparent, the color of the skin leaks out of the socks, making the socks a different color. This mix color is by no means what you want, but it cannot be changed.
Not only that, transparent thigh high socks can make the thighs lose the temperature, because these socks was too thin so can't keep the thighs at the right temperature. A pair of thin or transparent thigh socks is not a good choice when you like to hang out in the fall or winter.
Kayhoma thigh high socks are completely different. They are woven with underwear-grade cotton yarn, which is soft and comfortable. And their knitting density is twice that of ordinary thigh socks, so they will not become transparent. They can keep your thighs warm, almost the same as leggings. They are completely different thigh high socks.
