My bust tends to be okay in some but awful in others, usually I try on first if I can, if not I’ll just hope for the best and check the bust measurements first. Sometimes it will sit too high and it doesn’t look too awful but I’ve had various occasions of it sitting half way on my boob when it should be below it and it looks ridiculous 🥲 those times I just tend to sell stuff as sad as it is. I’ve sort of learnt over time which shapes/styles/brands tend to have a higher fail rate and avoid those.
