As I said in an earlier post, Moi-Meme has a beautiful Spring/Summer collection. And they have shirts now too! There are five to pick from, including the following:
Montreal Wide Collar

Cairo Short-Sleeved (I personally like this one!)
Shirts are available in both colours and solids and range in price between $95 US and $135, depending on the fabric, print, colour and sleeve length. According to the site, the shirts have a silky feel and are machine-washable.
I will have more pieces from Moi Meme in a few days.
