Read somewhere that almost 50% of women wear the wrong size bra so maybe a National Bra Fitting Week is a good thing. How many will go to be properly fitted is another matter.
The thing is I've been properly measured and fitted three times in quick succession and all three came up with entirely different sizes- one is very comfortable though so I plumped for that one being right.
As long as it goes around me without cutting me in half and the cups are big enough to hold 'me', my mobile phone, cash and front door keys I will wear anything that is comfortable.
The trouble is... all bras are different sizes and shapes, even when they claim to be the same.
Your breast size and shape changes right through your life, right through the month, when you are pregnant or breastfeeding (daily) and afterwards, if you put on or lose weight and if you change exercise, go on/ off contraception etc etc etc. As most women aren't millionaires with nothing else to do, I am not surprised most would be wearing the wrong size on the wrong day!! Lol.
You're right about size changing, Pixie....and often from day to day.......that's why I no longer have any bras. I buy bralets and they just wander around with me and my changing shape and size..... :-)
