As if starring in hit movies like Hairspray isn’t enough, Amanda Bynes can now count designer on her jam-packed resume. And she’s only 21-years old! At last night’s launch of her line Dear by Amanda Bynes at Manhattan’s chic SushiSamba 7 restaurant, Amanda told PEOPLE that she couldn’t be more excited to team up with Steve & Barry’s, the nationwide chain that recently launched Bitten, Sarah Jessica Parker’s clothing line. And the best part is, like Bitten, all pieces of the Dear by Amanda Bynes collection cost $19.98 or less. It’s almost too much for the young star to take in. “I, like, blacked out through the first part of this party! I can’t believe I am here doing this,” said the star, who wore a short, black racer-back Dear dress. “I’m all about Steve & Barry’s, and I am so excited.” The collection also includes jewelry. Amanda showed off her necklace, bracelet and cocktail ring to PEOPLE, enthusing “It’s all solid. Feel it? It’s really heavy. I like when jewelry is actually heavy. It is actually nice stuff. It’s so surreal!” Mark your calendars — Amanda’s line hits stores August 16.
