Thought I would just post this for info incase anyone else is struggling with sizing on some OD Denim.
I have possibly about 9 or 10 Iron Heart Shirts in a mixture of either L or XL's and mainly in Western Style due to a fairly slim waist against my Shoulder and Chest Measurements.
As a rule I've tended to buy OD Denim in XL, Regular Indigo in L, Kersey in L, Serge in XL and UHW Flannels in both L & XL dependent on individual dimensions which has worked for me up until now.
My new XL18 OZ OD CPO with 19.5 Shoulders and 23.3 Pit to Pit purchased recently was just a little bigger than all my other Shirts and although I didn't really notice this initially, (and knew that the dimensions of the Large were reasonably significantly smaller and wouldn't have worked for me either) I could definitely feel it after a couple of wears.
Although OD is regarded as completely Pre Shrunk I decided to do a Hot Soak in the bath about 60 degrees for 30 Mins with Woolite Dark Soap Powder to help preserve the Colour.
The result, Well I couldn't be happier. The colour is absolutely Vibrant, and looks brand New and I've almost lost half a Size between the XL and the L, with the Shoulder down to 19 and the Pit to Pit 22.7. The other dimensions have trimmed up in proportion slightly also.
I couldn't be happier. RESULT!!
Will send Photos when I can organise a Selfie Stick or someone to hold the Camera Phone.
