Many females don't have a clue about their correct size
Finding the perfect bra can be about as easy for women as it is for men to undo one.
A woman's boobs change size six times throughout her life and it's common to find the same girl coming up a different size in each store or label.
That confusion can mean accurately estimating your own size is almost impossible.
Some women use fitting room trial and error to get a look they like, while others book an appointment for a proper fitting from an expert.
But despite the amount of options on offer, a staggering amount of women still wear the wrong size bra every day - and it could be doing you damage.
To help women everywhere, we’ve taken a look at some stats to show estimation is no replacement for an accurate bra fitting. And below we've created a quiz to reveal if your bra size might be miles off...

How many women guess and get it wrong?
Two-thirds of women wear the wrong bra size, a recent poll found. And of those, almost a third purchased their bra knowing it wasn’t the right fit.

Where and when you’re born can help you predict your natural size - as well as what you drink
In terms of when you were born, those with birthdays in January, February and March are more likely to have bigger boobs - with an E cup average. But if you’re born in April, that figure drops down to a B cup.
Ds and DDs are the average for those born in June, July and November, while the rest of the months average a C.
Your choice of cuppa also apparently plays a part. Drinking coffee can actually make your boobs smaller, a British Journal of Cancer study found. Just three a day is enough to make a difference. They reckon half of women have a specific gene which links the two.
What sort of damage might you be doing to yourself by estimating your bra size?
Well, lots. The Chartered Society of Physiotherapy says that women wearing the wrong size bra are risking nerve damage, poor posture and pains in their neck, shoulder and back - plus saggy boobs.
