Smock-It - wear with everything, for every occasion. Make in solid linen and you will want one in every color possible.
Cap sleeve, 3/4 length, pleats at hem.
Shown in linen.
Fit: oversized, so make a smaller version if you'd prefer. Tip if you don't like the shoulders sticking out in cotton version, add a few pleats at the sleeve along the shoulder. Cute!
