London, April 8 : British women sure know how to make men swoon over them - a new study has found that ladies are working really hard on their bodies, thus making their waistlines shrink and boobs expand.

The study of 1,000 women showed that last year, the average bra size for British women under 30 was 36 inches, but now it has thinned to just 34.

Meanwhile, the average cup size has increased from a C to a shapely D, reports the Sun.

A spokeswoman for cosmetic surgery clinic Birkdale, which conducted the study, put the changes down to women taking more exercise, cutting down on booze and fast food - and simply buying the correct bra size, spurred on by TV makeover shows. (ANI)
