I've worn rope under clothing as well.

It was noticeable to me in the breast ropes because, well, I have an ample bosom. My rope bra was of a strapless variety, therefore my breasts took on a slightly different shape (aka my breasts looked ginormous and heaved outwards). I wore a loose sweater and I think some folks might have double took though not sure if they recognized why I appeared as such.

*note on safety- you run the risk of damage to keep a rope tight around the breast for more than 10-15 min.*

The crotch rope, unless you're wearing tight or fitted pants, is harder to detect. Skirts work well.

Karada is a great full body rope harness to wear for a duration, or at least that style 'bra' up top.

mmmm rope how I love thee
