@HB I felt the need to reply because this was one of my biggest concerns. I work for a small organisation in an office and did not want people to talk or judge me so I understand not wanting people to notice.
Anyway, I was a 32 a/ small b cup that had lots of empty space. I got 325cc partial. I’m 8.5 weeks post op and no one in my work has noticed at all. I used to wear a padded bra but believe it or not people just don’t pay attention that much. I returned to work 2 weeks post up and just wore a baggy shirt and would use my big scarf to cover myself up but to be honest it wasn’t necessary. Also, I went to a family dinner 2 weeks post op and wore a shirt- no one noticed. My sister that I live with hasn’t noticed (not that I walk around in a bra or anything but she hasn’t noticed in my normal clothes).
If you are really worried do something different to your hair to get the attention away but like I said, they won’t notice. And especially in your post op bra!
