Shirt or Blouse? Pattern Plays a Big Role

I used Butterick 5226 for my No 1. Ladies Detective Agency Shirt I guess it's the more fitted character of the princess seams views that cry blouse! to me. The others strike me as shirts.  

Vogue 8747 is still in print

Vogue 8747 - much like the front-of-the-bust gathered shirts that Lexie in BBC's Monarch of the Glen wore, strike me as shirts. So I guess being more fitted doesn't always say blouse....

*Simplicity 9857 (out of print). These garments, with their more romantic flowing lines, look blouse-like, don't they? Those front tucks are not at all crisp, so that must be it.

Vogue 2105 80's Blouse (out of print) Seems more blouse-like than shirt like. Why? Is it simply the way the pattern front styles the garment? Is it the deep open neckline? Perhaps it's the nearly hidden buttons and the somewhat formal, dressy look of these pieces.

McCalls 7360 is Out of Print

I'd definitely call this a blouse....McCalls 7360 (out of print), says soft, both in it's romantic flowing lines, and it's traditionally feminine, historically inspired collar details.
