You can buy them from the ladyparts.ic site (BigDaddyHurt's shop).
Items in the shop, such as Clothes or Sexbot Modules, will take several in-game days for them to appear in the shop after you install the mod (Based on RNG).
📝 Note: If you don't wanna wait for the RNG, All Modded Items can be spawned and added to your inventory through the DEBUG Menu (Developer tool).
