Teen entrepreneur Mary Kate Olsen loves to buy big, stylish jackets,
because then she can secretly wear pajamas in public.
The 19-year-old beauty, twin sister of Ashley Olsen, often goes out
with her nightwear on, and she keeps it all hidden under her over-sized
coats.
She says, "I love getting amazing jackets because you can wear
your pajamas underneath and everyone's like, 'Oh, fabulous jacket,' and
I'm like, 'You should see what's underneath!'"
