Hey,

That jacket is actually a few hues brighter than navy, which, in addition to it being linen, makes it an ideal for warm weather.  It’s unconstructed, partially-lined, has brown buttons and patch pockets, which can be seen better in this shot from a San Diego wedding last summer. 

Unfortunately, I can’t recall the maker.  Two summers ago, I ripped off the tag when trying to remove the dry cleaning tab.  The inside care tag is in Italian.  That said, here are several alternative linen jackets that I thought looked nice.
