It seems a Hawke's Bay woman was on to something when she shared a video online on Monday, documenting New Zealand retailers' lack of bras for women with large breasts.

Yesterday ONE News Now published a story that included a video of 20-year-old Charde Heremaia inside a Kmart store, frustrated she couldn't find a sexy bra to fit her FF boobs.

An outpouring of reaction to the story on the ONE News Facebook page all but proves Ms Heremaia's concern is no trivial thing.

Tina Sinclair was one of the hundreds of ONE News readers to share Ms Heremaia's frustration, writing: "Agree! Its so hard to find my sized bra (14DD) and when i finally find one, its bloody ugly and looks like a nana bra!!.. Not sexy at all".

ONE News reader Joanne Bentley also agreed with Ms Heremaia, writing that in her experience bigger bras are only available in specialty stores at high prices.

"It's an absolute pain that Farmers or any of the lower priced stores don't stock the bras that are available in specialty shops," she wrote.

Kellon Leef backed those sentiments, writing: "It has been a problem for far too long. Why are Size 16+ Clothing so freakin expensive?

"And DD bras are expensive and so disgusting, big woman can look and feel sexy in just the same design as too smaller ladies. It is a problem in the fashion industry. Something needs to give."

Another ONE News reader Teresa Hellier says she regularly has to buy "granny bras" through lack of choice.

"Happens all the time! I end up in granny bras! Most clothing for plus size people is so bland! It's like bigger people aren't allowed to feel and look sexy!" she wrote.
