No pictures here, since the t-shirts are now all at different stages of laundry and cupboard, but I altered 3 of my t-shirts to make them more wearable. Typically a commemorative t-shirt has some attractive picture on it, and reminds me of some cool event, but the un-contoured fit makes me rarely wear them, except in bed. All I did was contour the side-seams, including the arm holes. Now I have 2 extra t-shirts I can gladly wear to work. The 3rd t-shirt is a sports fabric, gained after running a 10K, but was so boxy I couldn't run in it. Now it fits well and can even be tucked into shorts if required.
Quickest way of increasing my wearable wardrobe, ever!
Of course the alternative, which I did with a Yellowstone t-shirt is to buy a Large or Extra Large men's T-shirt and totally remake the t-shirt with a pattern. That takes longer, but the final result does fit a bit better. The only trick with that method is to bit careful with the purchase, so as to make sure the neck is not too large.
