18 Nissan (Pesach)

Chazal tell us that Bnei Yisrael merited redemption from Egypt in merit of three things. (1)They didn't speak Egyptian (2) They didn't wear Egyptian clothing (3) They didn't use Egyptian names. If so why in Shemos 3,22 does it say that "Visha'ala... Klei chesef uklei zahav usmalos visamtem al beneichem vial benosechem vinatzaltem es Mitzraim" (and borrow...silver and gold vessels and clothing and put them on your sons and daughters and empty Egypt). Why would Hashem tell them to borrow the Egyptian clothing? They shouldn't start wearing Egyptian clothes now!
