Getting saggy boobs loosing weight

So I’m only 24 and I’ve lost a stone, got half a stone left till I’m back to the weight I want to be after getting married 3 years ago but for some reason my breasts are starting to sag a bit and don’t look as full, I’d put a picture up but I feel so embarrassed even though you don’t know who I am. Lol I dunno weather to leave loosing the rest and stay this weight as I don’t want to end up with really bad rocks in socks. 😂 My husbands not bothered and says they are lower then there were and not as perky as when we got married but I still love them and laughs when I get them out and ask him if there really bad. lol I can hold a pencil under them hands free now and I only used to put a bra on to cover up my nipples they were nice and perky and full. 😞 I’m guna get myself some nice underwear to make me feel a bit better and start doing breast lifting work outs, and using oils on them that help firm skin slightly. I’m not expecting miracles but if it helps a bit or stops it getting much worse then why not. Has any body else had the same issue? Thanks for listening to my rant
