Chelsea have launched a vibrant new home kit ahead of the 2021/22 season which features an eye-catching variety of patterns and yellow trim.
The Nike strip, in the club's traditional royal blue, was inspired by the op art movement of the 1960s which focussed on optical illusions.
Zigzags runs across the majority of the torso and right sleeve, while the left third has a chequerboard pattern. The shorts are blue and similarly patterned, and the socks white with blue trim.
The match-worn kit and replica jerseys are made entirely from recycled plastic bottles and will be worn for the first time as the Blues take on Leicester City in this Saturday's FA Cup final at Wembley.
Chelsea Women will wear the following day as they face Barcelona Femeni in the Women's Champions League final at Gamla Ullevi in Gothenburg.
Chelsea described their new outfit as "the perfect blend of style and substance with a bold new aesthetic" in a statement.
They added: "Inspired by the designs from the OP Art movement - the dynamic blueprint represents energy and vibrancy, synonymous with the new wave that is propelling the club forwards.
"This season's kit has a brighter, more vibrant blue with hints of yellow cutting through in the side-tape and swoosh.

"'CFC' in yellow is knitted into the back neck. This print is continued onto the shorts and the full look is complete with white socks featuring a sleek yellow and blue trim."
Meanwhile, Chelsea midfielder Mason Mount claimed the new jersey "is so unique from the others" he has worn and predicts it will be a "big hit with Blues across the globe".
The Three Lions star added: "I feel like it really represents this younger generation rising up the ranks and I love the sustainability behind it.
"It's really important to be mindful of our impact on the environment and it's great to see football leading the way on sustainability."
