Saggy boobs😭

So I’m only 17 and my boobs are a size 34E but they are literally down to my belly😭😭😭😭😭. It makes me self conscious and when I had a boyfriend I never took off my bra when we did stuff because I was so embarrassed with my body💔...

Is there anything that actually works to lift them and make them fuller as the base of my boobs aren’t full if u get what I mean.

And any advice for how I could wear bandeau dresses and tops.

If all fails I’ll probably just have to save up to get my boobs done😭🤦🏾‍♀️
