Major Discovery: New Planet Could Solve Fashion Crisis for Youngsters NASA reports a recent spotting of new Planet Blue Kids in Malibu. According to scientists, the boutique belongs to the same universe of beach-loving, rich-hippie style as its older siblings, only in smaller sizes. Antik Batik tunics and Gypsy ’05 maxidresses have been shrunk for minis. Other signs of life include Acoustic, Rock Baby Rock, and Lucky Fish lines for boys and girls. Delingos handmade toys and organic towels by 3 Sprouts add atmosphere. The discovery could be very important for future back-to-school shopping missions. Without the galaxy quest.
