Hiya sarah welcome babe!!
I didnt have 310 and i aint the same stats i had 380.
My stats are 5ft7″, just under 9st and size 8. I was a 32aaa had no boobage and now im a 32f/ff with the 380 unders.
I only LOOK a D/DD at most.
I did have pictures up but ive took them down!
The most important advice i can give is: tell ur surgeon u want to look a d cup not measure a d cup, as if u measure a d cup ul only look a large b small c. Also give ur boobs time to settle, i was the worlds worst i would post in ere constantly saying they were too small, now sometimes now theyve settled they are too big haha!!
Hope u enjoy the experience.
