Colleagues at Bramall Construction in Rotherham have been doing their bit to help Yorkshire Air Ambulance's BAG IT UP Bra Campaign.
Women employees from the housing and regeneration company donated unwanted bras to the campaign which is aiming to collect 200,000 from across the region.
The bras will be sold to market traders in the third world - and will help to raise £10,000 for Yorkshire Air Ambulance in the process.
Bramall chose Yorkshire Air Ambulance as its designated charity two years ago, and since then has donated more than £20,000 to help the life-saving crews stay airborne. Yorkshire Air Ambulance relies entirely on donations - and needs £7,200 every day to keep flying.
John Wilcox, Marketing Director at Bramall, said: "We've a few members of staff here who have family members that have been helped by Yorkshire Air Ambulance.
"Our head office is based in Yorkshire and we do a huge amount of work in the area so it seemed a really worthwhile cause to help when we came to choose a charity to sponsor two years ago."
Dress down days at work and other fundraisers have helped boost the charity's coffers further, and Bramall is due to give Yorkshire Air Ambulance its fourth cheque for £5,000 in November.
Several employees have also joined Bramall's 200 Club in aid of the organisation. Members give £5 a month from their pay with the chance to win £300 in a monthly draw, and £1,000 at Christmas. The club has raised £4,280 per year for Yorkshire Air Ambulance.
John added: "By the time the two-year sponsorship is up we will have donated £30,000 to the Air Ambulance and raised more through fundraising.
"We are proud of the work we have done with them over the past couple of years."
Paul Gowland, Fundraising Director at Yorkshire Air Ambulance, said: "We are very grateful to Bramall for providing ongoing support over the years.
"Without the generosity of companies and members of the public throughout Yorkshire, we would be unable to save the lives of the hundreds of people who have been rescued by our Air Ambulances. We look forward to working with Bramall in the future."
