I see these comments ALL the time, so perhaps I can help someone. Im 5ft 125 lbs. I bought a lg. according to the chart. I had never worn one. I had 2 friends help me put it on. Thats right, u CAN not do it right alone. That is the point, is to pull it tight to bring the waist in. I also have saggy boobs, my friends clued me in, u bend over, reach down and pull those puppies up. :) they will stay there and LOOK ..huge! I never felt so sexy in my life. they said MINE was too big!
