I’m on my 5th man shirt upcycling, I guess I like the exercise enough. Wrinkle it, ruffle it, turn it upside down, there are so many possibilities when refashioning a shirt.

I took a thick chambray shirt as a basis:

First thing, take away the worned out collar and cut the sleeves like a tank top.

Cut out the cuffs into triangle:

Pin it into the armhole.

Sew a zigzag stitch (leasier to sew than a topstitching)

Fold the remaining sleeve like an envelope

Pin it at the bottom to lengthen the shirt

Sew both sleeves and press

It gives a V-slot on the back

As the front is slightly shorter, I stitch together both shirt plackets

And this is me who enjoys the soft light of a summer evening.

Needless to say the enterprise was fun and gainful because I granted myself a new dress with zero additional budget and zero waste in a very short time You can see other recycling ideas here.
