Hey Abbie,
What’s your desired look? Lots of girls want upper pole fullness (seeing the curve at the top of your boob) so choose round.
I personally didn’t want this because my aim is to look at natural as possible, and I’m too flat for my own tissue to help give me that slope over the top of an implant, so really it depends whether you a) have enough tissue to soften the look of a round implant and b) want to go under the muscle.
I’m really happy my surgeon offered me teardrops as I knew they were less popular due to the risk of flipping, but they were what I went in hoping for. She’s giving me textured overs to reduce the chance of this movement but of course then there’s still the risk of ALCL xx
