BORIS Johnson’s new wife Carrie has been brushing shoulders with everyone from the Queen to the President of the United States at the G7 summit this weekend.

But the stylish mum-of-one proved that it isn’t necessary to spend a fortune to look the part, thanks to her RENTING nearly all of her show-stopping outfits.

In fact, Carrie Johnson, 33, debuted a wardrobe that would have cost £3,755 but she managed to hire it all for £217.

This follows Carrie opting to hire her gorgeous boho £2,900 bohemian gown by fashion designer Christos Costarellos, which she rented for less than £45 when she tied the knot with the Prime Minister last month.

The newly-wed Carrie certainly ensures all eyes are on her with her eye-catching looks – but it is incredible that she is promoting sustainable fashion in the process.

Here are her G7 looks and how much money she saved by choosing to hire them….

Mustard midi

Cost £265 – Spent £8

For her debut look in Cornwall, Carrie arrived in a £265 mustard yellow midi by Alice Early.

However, she rented the striking look from My Wardrobe HQ for just £8 for the day.

This was the same website that provided her wedding dress, and has a huge selection of clothing pieces, including jumpsuits and ball gowns, that could cost up to £250 a day to rent.

These pieces are both available on My Wardrobe HQ for £80 apiece.
