Simplicity 4760 - I used the same fabric for the facing and overlocked too it in dark turquoise. It is a tie dye teal deep sea-green Hill-Berg 100% cotton that looks very blue in photos! Clear buttons to suit the water effect. I'd like to sew a shirt with a collar stand separate to the collar next, I would also use heavy interfacing on the collar next time instead of medium.
I made this dress out of hippy fabric (bought 3 metres then charity shopped the fabric and this dress, fun but too bright for me!) I lined the sleeves/bodice in this aqua print. I used Simplicity 6094.
