Help with sizing please!

Dear Silver Bellers

OK, my yarn has arrived and I'm all ready to go. BUT, I don't know what size to make, medium or large. My bust is ample, granted, but can any of you knitted up silver belles please measure if you have made a medium or a large and tell me what the finished measurement around the fullest part of the bust is on these sizes please? I know the pattern says knitted measurements, but if that's the case I may have to do some jigging as I don't want the bust to fit and the rest to swamp me! The knitted measurements are too small for my bazookas!

Help please!

Love from an eager and ready to go Silver Beller
