Ladies, why do you wear stockings with feminine, lacy tops?

When I wear stockings, I choose ones with seams in the colour I require.
The colour is usually black but may vary depending on my choice of dress.

I do not choose the tops - some are plain, some lacy.
And you are not going to see which it is !
The stocking top needs to be robust to attach the suspender.

However, pretty lingerie does boost a lady's self-confidence, even if it is unseen.
