It arrived a few weeks later and promptly returned it (silly me forgot to take a photo) because the shoulders were way to oversized at about an inch either side (strange since this was their smallest offer). After having a look at other members who had bought a WPG here as well I can see that they had suffered from the same fate.
I was impressed with Magnoli's promo shot of their raiders shirt and the shoulders sat right to my eye, so I very recently had the custom raiders shirt made in 'stone' by Magnoli. It was a very pleasant process and the shirt arrived in just over a month's time.
What I did like is that the shoulders fit great and the sleeves started right at the shoulder bone so sat just right and didn't resemble the oversized shoulders I had previously experienced.
The colour however had a slight pinkish hue - I knew this from previous threads by Magnoli and other members themselves so this was not a big surprise but had to view it in person, the pinkish hue was more prevalent than a tan or stone coloured hue so I thought lets see what the KOSC colour looks like just to compare. I put my order for KOSC in 'light khaki'.
It arrived with another painless experience and my first reaction was - wow that's green, it reminded me of an old german military shirt I had. Even though I don't doubt it's SA authenticity it just didn't bring me closer to the colour. The fit however was shorter in length (I requested this) however the shirt flared out quite a bit (almost like bell bottoms) so I had a tailor straighten it out. As well as this I had about a 1/2 inch taken of the sides of both the stone raiders shirt and KOSC light khaki shirt for a more fitted look on both shirts.
I then decided to RIT DYE my 'stone' raiders shirt, I ended up using one small bag of RiT dye on it and as you can see it has come out a 'tea stained' colour. I much preferred the earlier colour. ;/ Sorry Magnoli.
As a professional photographer I thought I would document the shirts here so just everyone can see how they compare in colour. And in all fairness to all vendors the colour of the shirts are always (as many things) a highly debatable issue so I'm not here to throw stones at anyone, this is merely a depiction of my journey for your interest. All of us have a different understanding of is deemed to be SA.
The images were taken in 2 lighting conditions: 1) daylight adjusted flash power 2) indirect daylight through a window). I also did not colour correct these images and each set were taken on seperate occasions thus you will see the colour of the KOSC shirt remains consistent for comparison purposes.

Following below: with Rit dye remover on the 'stone' Raiders shirt, the KOSC 'light khaki' shirt remains untouched in colour.

So I'm still on the hunt for a raiders shirt that resembles a colour similar to what I'm seeing here:

So far in my mind it could be an adventurebilt or a todd's? Any suggestions? Feel free to comment.
To add a meme to the latter image: "Don't worry it's just a colour!"
