Ah, Mary-Kate and Ashley Olsen child stars who grew up to resemble eccentric bag ladies. The Olsen twins have been very productive postFull House. It's just that most of their achievements have nothing to do with television, radio, music or movies. They have developed a line of low-priced child and teen clothing for Walmart, a high-end label known as the Row and a contemporary collection called Elizabeth and James (named after their other siblings). They've actually become very successful fashion-industry fixtures (except for their tendency to wear ridiculously oversize clothes that look as if they were stolen from their grandmother's Victorian-era wardrobe chest). But a Walk of Fame star? Aren't the endless paparazzi photos, fashion spreads and magazine interviews enough?
