Fulham used to buy off the rack and put their own logos on I think. Then Nike did some deal with them which meant Nike would produce them properly but they could only have existing designs. So there'll be loads of clubs with that kit.
You're not wrong, think MK Dons have the same top as well.
I'm afraid to say that that Widnes top looks the dogs wotsits. And it's not irregular hoops, it's not "Hullish" either.
