I couldn’t agree more with Jessica – I was advised exactly the same having previously just assumed i needed implants! (there’s a picture of my current boobs on my profile now so you can see the sag element!) Regarding particularly option 2, i was told this is probably not wise for me, as for all but a few women, it just doesn’t give a long term result and more surgery is inevitable.
I have discussed sizes too and have similarly been told than 300 is the max for my frame for implants only but might be too much for me combined with a full uplift given I am already a decent C, so 275 should take me at least to a big DD. How large are you now?
