Wearing a badly fitting bra after being measured at m and s etc so aging.
Most of the armpit fat you see should be in the cup.Its not fat its breast tissue.
If you have to hold your boobs going up and downstairs it does not fit.
Boob or Bust bra measuring advise will sort this out! It takes 4 measurements.
If it rides up at the back the band is too big. It should be the same all the way round.
Is your cup right in the boob crease or sitting too low?
If your boobs pop out bottom your band is too big.
If you fall out a plunge bra your band is too big and your cup is too small.
4 boobs your cup is too small.
Look in the mirror can you see the gore (that bit in the middle) is flat against the skin or can you get a finger/fist in that gap ? Its too big in band if it is.
Get a good fitting bra and it will make you look a dress size smaller.
fyi you will struggle to then find your proper size in supermarkets and cheap shops.
cuts in under armpit and you want to fling it off after a long day it does not fit. You can be comfy in the right size.
Pop your bra on back to front straps not on and pull it away from your ribcage how many itches give do you have? more than an inch band is too big.

Read some threads all these questions have come up loads. I joined 2 years ago its been life changing. Even if it is a pita to find my size. Cup sizes are not the same on different bits of elastic they are in proportion to each band size. There are loads of posts from 34b how can i be a 28ff too.
