I already wrote how and where I found the wonderful material for the shirt of his desire.
It was exactly what BOAH wanted: traditional white flowers on a dark blue background. Even if he IS a courageous and very cool guy and wears colours other male probably wouldn't, we didn't want his first Aloha shirt to be too brightly coloured. I think this fabric is perfect.
So I had to find a simple yet perfect pattern with yoke and collar. I found one for free, but it was available only in size S/M. My BOAH is quite a tall guy, and from his belly you can guess he loves good food (as most Italians do) and cooking, so I needed at least a size L. After all the changes I had to make on the pattern, it was almost something new. However, if you would like to use the original small pattern and get help from a nice tutorial, have a look at Melly Sews blog.
I cut the front and back parts longer and sloghtly curved, as BOAH is definitely NOT going to wear the shirt tucked in his trousers as some men do,
He loves his shirt, and I'm very proud to se him wearing it. He looked very cool on our Italian vacation at his grandma's home next to the the beautiful palm tree.
Edit: I later shortened the garment a bit as it was slightly too long for a Hawaiian shirt. The shirt is still in use on hot summer days for that special summer feeling.
