I don't know if this will help. I did read where a user moving up to the, I think, xlarge domes. Used a bra to hold the domes in place. I think it was a nursing bra or she cut holes in the front for the airlines. May or may not work. May not provide enough pressure. Someone here like maybe anastatia might have a better idea. If you do have to order the smaller domes to use until you build up. At least you have the larger domes ready.
