The singer-turned-reality star has teamed up with a shirt designer for The Peter Andre Collection.
"I am thrilled to be launching my new clothing collection," Andre said.
"The modern man likes to look after themselves and I am no different. I am proud to be offering a new range for them to choose from.
"The children's collection is just the beginning, with another collection coming out in late September 2012 which will be much bigger and I am very excited about."
Included in the range are Italian-made white and black shirts with contrasting collars and cuffs, greys with black and white details and pale blues and pinks mixed with florals.
Also available are T-shirts featuring skulls with Australian hats and British Bulldogs.
Children's clothes available in the range include three round-neck T-shirts with 'Lazy Bones', 'Daddy Rocks' and 'Daddy's Little Princess' designs.
The clothes will be available from Peter Andre's official website from tomorrow (July 6).
Prices start at £24.99 for the men's range and £21.99 for the children's range.
