My Clan Graham is high quality garment and its history even more important, Clan Graham fought for the right to wear kilts and won. Clan Graham, Duke of Montrose are advisors to China on renewable energy. Heavy duty Cotton. The design and colours are superb, I feel very proud as a Graham descendant from Appleby Westmorland Cumbria to wear this especially when wearing of patches is banned in Aotoearoa - New Zealand. Kiwis wear all black as the t shirt is with Green lettering to match the environment and yellow for joy and purple thistle to match my hair. The wardrobe police know who my Clan is now !

Comfortable fit and well made shirt. . I was really impressed with how well the print came out considering it was from a photo of my original art work. Appears to wash well so far too.

The tee shirt was of good quality and the photo true to original. The printing was just fine, as usual.
