My husband bought this shirt a little while back after spending about two seconds in the fitting room and not hating it (yep, typical male shopper). The first time he actually wore it though, he realized it was just too tight across the shoulders and a little too short as well, with his white undershirt peaking out from the bottom. Sadly (for him, not me), this means it ended up in my refashion pile.
I decided to go the sleeveless button-down route that is in style currently. First, I used my trusty seam ripper to remove the pocket. That'll get in the way of my bust darts later.
Next, I chopped off the sleeves. [Not pictured: I trimmed in a bit more off later so the shoulders would match my shoulder width, instead of being just shy of my husband's.]
I took in the sides.
And, as I eluded earlier, I added a couple bust darts to reduce gaping at the armholes.
Finally, I used some of the scrap from the side seams as binding to encase the raw sleeve edges, and I was all set!
