I got this chambray shirt form Nordstroms and I've been wearing it whenever I don't want to think too hard about my outfit.  It can be styled with pretty much anything (although I do have a tendency to style it with red) and look fantastic and the button is perfectly placed for no gaping by the boobs (something I have infinite problems with). So I of course bought it despite its (not too) ridiculous price. No boob gaping is worth it.
