upcycle a big shirt into a dress/cover up

I found this size 4x woman's cotton shirt at a garage sale and thought it would make for a very cute cotton summer dress.  It's very casual and perfect to use as a swimming suit cover up also.  Here is the before:

 

 my computer won't let me rotate these pictures :(

I started by cutting off the sleeves leaving a little around the seams so I could hem the edge.

I turned it inside out, put it on, and pinned the armpit where it would fit me.  Then I took it off, pinned down the side at an angle to the bottom hem of the shirt, and cut off the excess.  

Next, I pinned and sewed down the raw edges all around.

That's it. It's cute and comfy.
