The pair produced the designs in celebration of BBC Children in Need Rocks concerts being held in London which are curated by Barlow.
Speaking about the collaboration Barlow said, “BBC Children in need is a cause close to my heart and for each campaign we think up new ideas to top those from years before.
“As one of Britain’s most successful designers, Paul Smith was a stand-out choice for the project and I’m thrilled that he agreed to do this without hesitation, helping to support young people across the UK.”
Smith added, “It’s absolutely brilliant to contribute to this fantastic cause. We hope you like the range, please buy them and support the great work the charity does.”
The items are available to buy on PaulSmith.co.uk, at the concerts and in selected Paul Smith shops.
The two concerts will take place on November 12 and 13 and will feature performances from Robbie Williams, Bastille, Ellie Goulding and more.
