Please help me decide on 400cc vs 425cc vs 450cc high profile silicone using the dual plane technique? (Photos)

Hello! Intern medicine resident here finally scheduled for BA 3/9 Yay! I'm well aware this is highly variable and the differences between 400, 425, 450 are nuance at best. Given that I am 25yo, 5'5ish, I live around 115-120lbs, no kids or hx of breastfeeding nor desire for either in the future, exercise consists of yoga 3-4x/wk, current size is 32C of 34B with ptosis and wide sternum, what are your thoughts? Final sizing tomorrow. Thanks in advance
