Yes, yes, I really do hand stitch these 2 shirts together, all through the cuffs and the collar and the lining. This has both the original 2 collars integrated, as well as the cuffs from both shirts. My girlfriend said having 2 cuffs on each side feels like rose petals around the wrists. Nice! I have embroidered onto my custom label that this is the 90th shirt I've made, #90 in the 'series', made in 2020. And the 'key' is WS, which means it is a 'western snap.' I love the western touches, the yokes, etc. I've made a few dozen of these doubled-up shirts, first for myself, and now for you! Buy one, I’ll make more! But these are one of a kind, each ‘design’ doesn’t come in different sizes. I buy shirts individually on their own merit at the goodwill, at home I have many to choose from, and the serendipity happens when I find two shirts that compliment each other and they line up nicely to make one warm, unique, upcycled shirt! 

Why do this doubled shirt thing? Because I’m a skinny-ish guy brought up in both the chilly midwestern tundra and the fog of the Bay Area, for years I’ve been lining my pants and stitching two shirts together - to make one - for warmth. 
I can’t help it, I’m a maker and necessity was the mother of this invention. 
I'd say this is a classic small, in mens sizes. My best google search tells me that a this might translate to a women’s size 2-4. If you think of it as a ‘boyfriend shirt’ and roll up the sleeves, I promise that the stitching around the cuffs will be nice to look at!
I’m proud of my work. The attention to detail/stitches per inch may look OCD, but I just want to do the best job I can.

Care: I put this shirt through the washer and dryer normally, it actually helps the shirts settle in together to do it this way. But if you want to hand wash and line dry, that might be better now that the 2 shirts are synced together. 

You can be confident that this one-of-a-kind wearable artpiece has been made with care, by me and just me, giving new life to discarded clothes. You aren’t going to run into anyone with the same shirt, that is for sure!!
