Wtf, Lands End?

See those two sweaters? Both of them are Lands End long sleeve cashmere cardigans, in a size medium. Both are from last year's line, bought on clearance plus 30% off (champagne taste, beer budget). I have owned the top one for about a month and I've been wearing it regularly. It's been carefully laundered, and has not been shrunk. The one below it is the same sweater, in a size medium petite. It's about 5 inches bigger in the torso, and has deeper armsceyes, longer sleeves, and a longer body. I am absolutely swimming in it. This is absurd, and it's going back. I don't care if I'm a size small, medium or large, but I'd like to know that if I buy the same garment from the same year in the same size, THEY WILL FIT THE SAME WAY.
