Knowing the limit is the key when trying out a transparent trend. A little is the peek of elegance, and a little more than that is utmost vulgar.
The less the better is what I think. If you have a transparent top, pair it with solid pants and visa versa. I came to realize that Dolce&Gabbana are very sleek when they create transparent clothing.
For example I own a classic, lace, black dress, ankle-length from them, in which I only spotted some transparent bulks along the sides, about a week ago (after wearing it more than three times.) That’s what I call genius; you have a hint of provocative beauty in a very subtle, classic look.
