Based on the quotes, copied below, from the CFL link provided by ramonecat, I think you can bet the mortgage that you won't be seeing any long sleeves or anything else in the way of an historical look on these Signature Uniforms. The league has already done retro for a couple, or more seasons. My guess would be a tiger skin print for the Cats and I've had a gut feeling, for some time now, that the RedBlacks will be wearing lumberjack plaid.
Those quotes, that make me think these thoughts:
"innovative looks" ....... "the CFL Signature Uniforms are intended to be bold and eye catching and push the envelope" .....
"These are complete uniforms – everything, from head to toe, including helmet, jersey, pants, socks and even gloves – and they are entirely new" ....... "Each one tells a story about its team, what that team stands for, and the fans who stand with it" ...... "Fans got a bit of a sneak preview of the approach when the BC Lions debuted their new CFL Signature Uniform a year early, in 2013" ..... "today’s CFL is poised for a bright and bold future" ...... "These new uniforms capture that spirit and reflect our momentum" ...... "It’s going to be a lot of fun to see our teams proudly wear them and our fans react to them.?
I certainly would be interested in hearing the designers' explanation of how those Lions' Signature outfits "tell a story about the team and what it stands for."
