I do not think this dress runs large. i think it it is true to size. i am usually a size 10 and a 34dd. definitely curvy and tall at 5'8. the large was perfect for my bust. i ordered a med also, and it looks really narrow in the waist. length is below knees as pictured. i was finding that the zipper under left arm is very catchy. i even checked the med and it is worse. that concerns me, but love the dress so i am keeping the large. length is so hard. i hardly ever find a dress the hits a little
