Hey, I’m 9DPO and I also had Dr Fiumara. I’d wanted 375/400 but the 400 didn’t fit so I ended up with 350/375cc. I have to say I’m really happy with the size so far and tbh wouldn’t want them much bigger, however I am very slim so I think it really depends on your body type and what will suit you.
If you’re unsure then definitely arrange another consultation with Dr F where you can discuss sizes a bit more. All of her results I’ve seen look incredibly natural though so I think you’re in safe hands, she’s amazing! x
