A Japanese firm has invented a talking bra designed to give the wearer uplifting messages.

Its makers say it contains sensors which can pick up nervousness in the woman’s voice or an increased pulse rate.

Tiny speakers built into the stitching then deliver encouraging messages such as: ‘If you give it your best, you’ll be okay! Go for it!’

A participant in the Walk the Walk charity marathon wore a film reel themed bra this weekend - but now a Japanese firm have invented a talking bra which gives women wearing it uplifting verbal messages

The new bra delivers encouraging messages such as 'If you give it your best, you'll be ok!' and also allows the wearer to record ow many steps she has taken or how many calories she has burned (stock image)

Or if a wearer asks, ‘Do I look beautiful?’ the bra will answer ‘very beautiful’ or ‘totally radiant’.

It can also be plugged into a smart phone, allowing the wearer to record how many steps she has taken, the distance travelled and the number of calories burned.

The Wearable Womanliness-Boosting Bra was unveiled in Tokyo last week by lingerie firm Triumph.

It comes at a time when the Japanese government is trying to boost the economy by encouraging more women to work.
