Is a simple, quick project, I love how the design of button holes and the easy knit with st-st and garter stitch.
Is lovely !!
(P/S: It can be finished fast but in between I was doing test knit for a project and some days not doing knitting)

I have using smaller gauge yarn / needle. My end result is not too oversize, but it fit me well.
I love this simple and relax yet intelligent design.

** I am happy with the outcome, is another lovely summer wear for me :D
