'Help! Need 32F plunge style with stretchy cups': The forum where 13,000 women are seeking desperate advice on well-fitting bras

Standard bra sizes have barely changed changed since the Thirties, but the range has expanded - making bra shopping and fitting a confusing and exhausting exercise for many women.

However instead of waiting for standard A/B/C/D cup sizes to evolve, it seems women are banding together to solve their biggest bra problems themselves in a forum called A Bra That Fits.

Nearly 12,800 women use the thread, a subsection of Reddit, which is dedicated to helping women find their correct breast shape and true bra size, while offering measuring and shopping advice.

A Bra That fits: Nearly 12,800 women use the thread, a subsection of Reddit, which is dedicated to helping women find their correct breast shape and true bra size, while offering measuring and shopping advice

According to a 2011 study, 85per cent of women are wearing the wrong size bras. And A Bra That Fits stands by a simple motto: 'Because everyone that wants one deserves a bra that fits.'



Cup sizes are based on two measurements — the breast at its fullest point, minus the rib cage measurement. A one-inch difference, will give you an A cup; a two-inch difference, a B cup; and so on.



However this approach doesn’t account for different breast shapes, which frustrated women are well aware of.



Questions asked on the forum, such as, 'Need help finding 32F plunge bras (and other styles) with unpadded stretchy cups for my sister,' or ' Omega-shaped and a 32K/KK? Any ideas at all, please? ' are answered with detail and precession.



And the forum's ability to connect such a diverse group of women with specific quandaries appears to be paying off.

The major American intimate apparel manufacturer, Jockey, recently announcement it is getting rid of A/B/C/D cups altogether.



Instead, Jockey's Volumetric Fit System will measure the volume of a woman's breast, as well as an under-bust measurement, with the volumetric sizes running from 1 through 10.



Using Jockey's flexible plastic measuring 'cups' in varying shapes, women try each one on for size to see what works best - or has the least amount of 'spillage'.
