If you have "deflated mom boobs", this probably won't help the way you are wanting.  It will just push your breasts out of your bra if it's a demi cup or balconette.  The bottom half of these is about and inch and a half thick tapering to pretty thin at the top.  When I say these are somewhat small, I mean the overall size.  They aren't as wide as my DD/E cups, but closer than any others I've tried. If you have a full covering molded cup bra and you're wanting more projection, these might work for that.
 I want to add that the customer service I received from this company was wonderful.  I received a generic purchase follow up letter from them that mentioned the fashion tape.  When I informed them that I never received the tape, they gave me a suggestion as to where it could be. When I informed  them that it was not there, they offered to send me a replacement which I received promptly!
