The so-called beige tights are natural leggings with velvet inside. From a distance, it looks like you're not wearing it. Up close, I can only see that you are wearing a pair of stockings.
Beige tights are socks with the same skin color. The skin color here is not the kind of socks sold in the market, but socks close to your original skin color, thus achieving the effect of barefoot. Beige tights generally have two layers, and the colors of the two skin colors are superimposed to achieve your original leg color.
The real beige tights are a little transparent, not simply thickened stockings. Its essence is a kind of fake meat-permeable leggings, with some reflection outside.
