Photoshop. It's the same style as the kits people make for (and I'm sorry to bring this up) Football Manager.
I have no idea and it sounds like others know more than me, but that image is just made by someone in his spare time on a PC.
They key question though is who is this person and are they in the know.. Personally I quite like this design, maybe with thinner stripes though
Someone on Twitter (I know, I know) said they were in a photoshoot modelling the kit and that's how they described it, someone on SaintsWeb made that image based on their description, and a few people who actually know on there said "yeah that's about right".
I hope the away kit is like the sash one we had - I still haven't got hold of a 125th anniversary kit.
Want something like this for the away kit http://www.footballkitnews.com/wp-content/uploads/2012/06/New-Lille-Jersey-2012-2013.jpg
On the Portsmouth mugs - I don't know! I didn't take the picture, I found it on the internet, though I would like to know the answer myself.
Oh stop it right now. I predict a return to this classic: please log in to view this image And the best Saints have ever been. Well, after KK had left, but it was the same kit.
When you say classic, I assume you are not referring to the hair? One or two of our players might struggle with that.
