My DD18 asked for a medium too...I'm just concerned they run small. She's about 5'6" 135....Ordering online at Citysports.com ..they have a 30% coupon . Brings the price to $115..
As I'm debating size, my other DD22 says..."hey you found that on sale, i want for xmass too!"
Thanks everyone for your help! I ended up ordering a large..that way if she wants to layer something underneath she'll have the room.
