Macca's is going from fast food to fashion with a limited edition line of activewear to mark the upcoming Rio Olympics.

McDonald's Australia has created "Maccas Legendswear" with Australian fashion pair We Are Handsome, which went on sale on eBay last night.

All proceeds from the eBay sale will be going to Ronald McDonald House Charities.
The activewear features a limited edition hooded vest and a pair of track pants.

The fast food chain has been calling on fans to "dress like a legend this Olympics" with the activewear on social media.
