If these came with a leather shoe attached with a 4½ to 5 inch heel, I doubt I would ever take them off. The "tight" suggesting they are not so much small, more super stretchy, that happens to be a very alluring attribute. (Which may be why they might actually be suitable for cycling. ) Not that I would wear such an expensive/attractive garment for cycling.
As with my H+M versions, either the outline of the mannequins underwear or the shape built into the model, made the details of the undergarments visible. I'm thinking (for a girl) a very fine string type thong - or 'commando' for that clean look. Another reason they might be more popular with the younger rather than older woman; modesty. Mrs Freddy won't wear anything like it, despite her 'respectable' shape. Probably just as well, given my age.
