"This Fyre Festival-branded clothing and other items that were seized from Billy McFarland were originally intended to be sold at the Fyre Festival itself but were kept by McFarland, with the intent to sell the items and use the funds to commit further criminal acts while he was on pre-trial release," US Marshal Ralph Sozio said in a press release
"The proceeds from the sale of these items, all traceable to McFarland's $26 million fraud, will go toward the victims of his crimes," he said.
The online auction lasts through August 13, and bidding on the items looks to be competitive.
Several Fyre-branded hats that were initially listed at $15 are already up to $200 to $300.
The Fyre Festival, a music festival set in the Bahamas, was advertised by social media influencers, including Kendall Jenner and Bella Hadid, as a weekend of sun-soaked paradise among celebrities, private yachts, five-star chefs and musicians.
Star artists Blink-182, Migos, Lil Yachty and Major Lazer all were billed on the festival's lineup.
Tickets to attend the festival had a price tag to reflect that upscale pitch.
But those who shelled out thousands of dollars for tickets were instead treated to mass disorganization, half-built tents and skimpy food options on a largely undeveloped island, leading to "Lord of the Flies"-type chaos.
