tbf, Castore and Everton should be very bothered.
1st off its Castores first kit with us, a chance to make a real impression. It's pretty crap for a first kit.
Secondly its our last season at Goodison. Surely they could have come up with something more classy. Even if the collar was all white and remove the wierd tyre marks on the pattern.
They've had a long time to come up with that design and it's not exactly inspiring. I don't hate it, I just think it's a bit "meh" and surprised that for their first Everton kit, that was the best Castore could do.
I guess the data probably tells them that it doesn't really matter what the kit looks like because people will buy it anyway - parents for their kids, other parents pressured into buying for their kids when their mates have all got it, etc.
That's likely why barely any thought ever goes into the kit design.
I reckon, if that's the kit - which it appears it is - it probably took about a day for Castore to draw up the design and send it to Everton, who likely immediately signed off on it.
Any ambitious club would have had a special edition kit lined up like. You can bet Liverpool would have.
