Good news girls, new research has found that while we are getting slimmer our boobs are getting bigger.

Research by the Birkdale clinic found that last year the average bra size for women under 30 was 36 inches but now it is 34 inches.

The average cup size has risen from a C to a curvy D.

A spokeswoman for the clinic said that the change is down to women exercising more, cutting down on booze and fast food and even just buying the right size bra.

Let's hope the changes stop there though, we don't want a nation full of Jordans running around!
