Aloha shirts are like womens' shoes—you never seem to have the right color or style on hand for that certain upcoming occasion, so it's best to continually add to your collection when you get the chance. Right now, I've got way too many super-collectible Shag and Disneyland shirts, so I need to diversify and get some cool shirts not necessarily purchased at Target.
The Hanna Shirt Company finds and then resells fine vintage aloha shirts on their website. Their taste in clothes is excellent: the merchandise is the kind of stuff I fantasize about finding in local thrift shops but never do.
The site is organized well and you can search by size, which is important for me because I hate it when I get teased finding an excellent design that ends up being a size too small.
