Pictured from left to right...
Hayaku, wearing baggy clothes because even in the book, his clothes are twice his size and he likes it that way.
Sarikah, wearing amazing maternity clothes and all their stretchy wonder because she's pregnant.
Yusu, wearing a load of tie-dye because she always wears flowy, bohemian clothes. (Even in the book; she wears caftans and sandalwood beads in her hair.)
Aya, wearing manly clothes for manly men. Because he is manly, dammit. (This is a running gag in the book; he's always over-asserting his manliness. Why? Because Amaya emasculates him somehow.)
Me, wearing what royal women might wear in the book.
Lochan, wearing scrubs because they're for doctors, which he is one.
Amaya, wearing sexy nightclub jeans. Because he'll be damned if he doesn't look hot.
