I am by know means an expert on the Lakota language, but after a little bit of research I believe I have an acceptable answer...
The verbs "wasté" and "ȟópeča" both mean "to be beautiful", so by adding the stative pronoun for second person, "ni-", we can generate the phrase "you are beautiful":
Niwasté (you are beautiful, more of a general term, can also mean "good" or "nice") - pronounced "nayeewahstAY"
Niȟópeča (you are strikingly beautiful, more "specific") - pronounced "nayeeH*Opaycha"
*the H (ȟ) is pronounced with a rasping of the throat, almost "hkhk", really fast. It's rather difficult to convey, but a simple "H as in house" sound will probably suffice...
