There are so many factors that influence how I perceive 'them':
Do I feel cold or warm? (If cold they are really tiny

)
How do I stand? (Shoulders squared - they seem smaller)
Mirror or photo? (Mirror usually bigger, but not always.)
And if photo, what is the vantage point / angle (low vantage point - they seem bigger).
Do I see whole of my body or just chest area? (Only chest area - bigger.)
Etc...
Interesting thing is that in time I somehow get used to having bigger breasts and what I would have considered big in past is quite OK right now...
I came to conclusion that there is no way I am objectively able to assess my newly acquired and evolving assets
