The Liverpudlian singer, who was eliminated in the first week of the live shows, is helping to promote the fashion retailer's "timeless striped knitwear".
"We asked musician Mr James Michael, from Liverpool - home to The Beatles - to model five looks that we think work rather well. You might recognise Mr Michael as a contestant on the British version of a little TV show called The X Factor," says the site.
"Why, you might ponder, feature someone from that show on Mr Porter? Well, we understand your concern, but we thought the 20-year-old, who was harshly kicked off from the first live show, had a nice little look going on. And an abundance of charm.
"So here he is, posing for our shoot, in the midst of a hectic schedule of performing at small gigs around the country and recording some tracks he's written with just him, his guitar and an iPad."
Michael told Digital Spy after his X Factor elimination that he was hoping to put together a "good, really big, nice band" and head into the studio in 2012 to work on his own music.
