In sims 3 آپ don't buy clothes! آپ can just click on the dresser and choose desing outfit (or something like that... I don't have the english edition so I don't know the exact command!) And once you're there, آپ can design 3 different outfits for each category~ And if آپ click on your sim آپ can change the outfit he's wearing!
Your سوال is quite ambiguious, so I'll give آپ two answers. 1) In the game, آپ can't buy clothes anymore. آپ buy a dresser, click and select "Plan outfit" and then آپ can create new outfits for them (you can have a max. of 3 for each catagory) 2) آپ register your game at thesims3.com, redeem your Simpoints, and buy clothing from the store. (or آپ can google "free Sims 3 clothing download" and get some clothes from there, but i prefer the official Sims 3 store)
Buy a closet then click on it and it will say change outfit and soomething else under so click on the thing under then u can change the outfit and add outfits and everything
