New measurements ( before running the track) lol
1. 29" as tight under bust as the tape measure would let me
2. 30" regular under bust
3. 37.5" standing up about breasts
4. 39.25" leaning around breasts
5. 37.5" breasts while laying down
What size do you think I am?

Based on measurements you're around 30G/GG uk size. Since you don't have much squash (difference between tight and snug) you'd probably be more comfortable in tight 32 bands and loose 30 bands. So that would be around 32FF/G. Since you're no experiencing that much guadraboob in your 32E, I'd say start out trying 32FF/G.
Good luck

Thanks! These are all uk sizes right? Any brands better then others?
