I'd imagine Steve Ellis is blissfully unaware that his name will forever be linked to Dundee gang culture.
Back in the good old bad old days (the 70's) when all of Dundee's gangs paraded around in, and did battle in their gang jerseys...these garments were referred to as your "Stevie Ellis" jumper.
The main design feature of a Stevie Ellis was that it had a high v-neck. This meant you could wear the jersey without a shirt underneath and it would still look smart, although most guys (and gals) wore Ben Sherman shirts with the jersey despite the fact you'd only see a wee bit of the collar poking out the top!
Being exclusively a Dundee concept meant you couldn't go and just buy one from a shop in the high street. They were customised to order. The best quality Stevie Ellis's were made at a shop called The Sewing & Knitting Centre, in Victoria Road. They'd gladly make a gang jersey for you in the housing scheme of your choosing!
You can find a few of the gang jersey colour variations in the Retro Archive, but the example above is the hooped colours of the Mid.
The top picture is the man himself wearing the jersey that inspired the cult clothing.
And for those younger ones who don't know who Steve Ellis is, he was the lead singer in a pop group called The Love Affair, who had a few hits in the late 60's.
