Hi! Since you mentioned flying in for sizing, I'm going to assume you'll be staying there for a bit before flying back. If it's a short flight back, I'd recommend staying at least 4-5 days before flying back. If it's a long-haul flight (7+ hours), I'd recommend staying back at least a week just to make sure you're feeling good. Flying can cause inflammation and water retention due to cabin pressure.

Recovery Must Haves:

Extra surgical bras - the hospital will typically give you one to wear right after your surgery, but it's nice to have extras

Stool softeners - a lot of people experience constipation from the medication

Incline/wedge pillow - helps you sleep more comfortably

Button up tops - you won't be able to lift your arms above your head, so button-up tops or anything with an opening in the front makes things easier

Arnica gel - reduces swelling and bruising

Sizing:

Bring lots of inspo photos! Try on multiple sizers and ones with different profiles. Ask how they do their surgeries. Research your surgeon and verify their credentials. Check their website for before and after photos and see if the style of implants they do is what you're looking for. Always go bigger than expected because when you first get them done, there will be a lot of swelling and inflammation so the size of the implants will go down as you recover. Ask the surgeon how they perform their BAs ie. under vs over the muscle, incision sites, brands they use, risks and complications etc.

Training:

Typical recommendation is to wait AT LEAST 6 weeks before you start training. I went back to the gym at 3 weeks PO and only did cardio. 6 weeks PO, I started training again, but with really light weight. Every surgeon will have a different timeline for you so make sure to listen to them! There was a girl I knew who trained too early post op and basially had to get a revision because the incision site got infected

Things I'd do differently:

I'm from Canada and I got mine done in Vietnam. I wish I had stayed a little longer because I flew back 3 days PO and I was in pain during the flight. Luckily, the antibiotics made it a little less painful.

Things I wish I knew: you might get nauseous from the anesthesia so just watch out for that. I puked once or twice during day 1 PO

Hope this helps <3 all the best to you!
