It is available to buy through Tommy Hilfiger's online store in the US, however it will not be available in Australia, with a representative from PVH Brands Australia, which manages the Tommy Hilfiger's Australian distribution, telling Fairfax Media the line has been "specifically developed for the US market".

This is the first designer collaboration for Runway of Dreams, a nonprofit started by New Jersey mother, Mindy Scheier.

​Scheier started the organisation in 2013, when her then 8-year-old son Oliver, who has a rare case of muscular dystrophy and uses a wheelchair, wanted to wear jeans like his friends at school.

The mother of three, who has a background in fashion design, altered a pair of jeans to go over her son's leg braces, however the design meant she had to go to Oliver's school at lunchtime to help him take them off so he could use the bathroom.
