Hello, i 5’4 and size 8, really petite chest width. I was given the same 275 / 300cc to choose from, i was so so so nervous on the run up to my surgery as i went with the 300 on my surgeons recommendation that going under the muscle they would be natural looking and the difference between the two is literally 25ml. It really helped me to actually measure out 25ml of water into a cup to see what i was driving myself nuts over lol!! I am now 6 weeks post op with 300cc high profile under the muscle and they really do look amazing and so proportionate to my body. Seriously, i was so concerned about being too big, but they do not look big at all once they are under your muscle / tissues. I actually think they look quite modest and dare i say it, i probably couldve gone a bit bigger.
25ml difference between the two will not be noticeable in your body, dont stress about it just go with what you think is best xx
