How to make my breasts less saggy and fill in gap? (photos)

d_el_h.      I appreciate your concerns, and from your photos, it appears that you are an excellent candidate for Mastopexy, breast lift surgery. Only skin is removed, your nipple areolar complexes can be reduced and moved upwards, and it appears that you have ample breast tissue to provide cleavage. Perky breasts without implants can be accomplished. Be sure to consult with a board certified plastic surgeon. Good luck!

Hello and thank you for your question. Based on your photograph, you are a
great candidate for a breast lift.  This can be designed to result in an
improved shape and contour of your breasts while minimizing scar
appearance.  Make sure you specifically look at before and after
pictures of real patients who have had this surgery performed by your surgeon
and evaluate their results.  The most important aspect is to find a
surgeon you are comfortable with. I recommend that you seek consultation with a
qualified board-certified plastic surgeon who can evaluate you in person.
Best wishes and good luck.
