While not the precise shirt Meghan is carrying, the Maeve Blouse from Anthropologie is offered for £101.30 or $120. 

It encompasses a related stripe, albeit in a crimson motif, and a tie-neck design that may be worn right into a pussy-bow, or copy Meghan and go away it unfastened. 

This shirt, nonetheless, options two lined buttons on every broad cuff on the wrist.
