MY breasts are really big. They are heavy too. I wear a 46-O bra. It has five rows of hooks in the back and four columns of eyes. I wear it on the second column. It has slings in the cups and a heavy band across the bottom, The straps are thick and double-reinforced and have additional pads that sit on my shoulders. It is hard to put on. Sometimes my boyfriend helps. When I take it off at night my breasts fall onto my lap. I play with them for a little. He does too, His soft and gentle hands feel so good.
