Crossbreed supertuck.... period.
I've used 3 diff IWB holsters, two of them being bianchi's and I can tell you the supertuck trumps them all in terms of comfort.
You don't really have to worry about tailoring your wardrobe to you carrying if you're carrying a gun that small + using an IWB holster.
I'm 5'10 and 155lbs and I've carried a full size 1911 and a glock 22 while wearing fitted clothes. But then again I carry on my 5 o'clock so that helps tremendously. With a G26 and IWB you can pretty much carry it anywhere on your waist and wear anything without having to worry.
