None of the sexy NPC clothing exists as player items. No fishnets, zip crotch knickers, stockings or transparent jackets. Every clothing item in the game has been spawned in and catalogued by the modding community. TBH the sexy options are pretty lame. You are never going to look like a Mox or that NPC you see with a see-through jacket and tape over her nipples until the modders find a way to work around the fact these do not exist in the loot pool.
If you want to preview existing clothing, someone has made a website. Its missing some set designs but they are just recolours. https://cp2077.8713.su/
