They are handmade by Kathleen Davies in her workshop in Connemara. I think she's looking for likes on Facebook, where you can also see her ceramic jewellery and wind chimes, if you are so inclined!
I also found this vintage pattern in a little shop in Clifden.
What is going on with the model's hair??? Mental.
Also(*thinks outloud*) I started thinking that maybe it's just an inferior version of a Hawthorn and maybe I'd prefer to make Hawthorn with its darts and pretty collar. Hmm ... To Be Decided.
But, either way, a shirtdress will be manufactured and seeing all Hawthorns online made me think about shirtdress fabric. I think shirtdresses are cool - for me to avoid the housecoat or nurse look, I'm thinking above the knee and a punchy print are in order.
