I've carried a Glock 26 for the past 13 years, most often in a tuckable appendix carried holster with a single belt attachment and a straight drop.
After I lost a bunch of weight a couple of years ago, I could finally carry behind the hip, but I find appendix much more concealable and comfortable.
At my son's wedding, I carried a P3AT under the bra strap in a handmade holster, just under my arm, while wearing a sheath dress. It worked really well, and thus I have fallen in love with the Marilyn holster (from Flashbang / Looper Leather) because it puts the gun in the same spot, with a well-protected trigger and a simpler draw.
Lots of other ways to do it.
