If you are between measurements, go a size smaller.
I have to admit, I first holstered the gun the way I would normally draw it, took two steps and said "nope", then tried to sit down and said "heck no". But, if you flip the gun so the grip is pointing forward away from you it fits a bit lower and ride "up there"! You have to twist your wrist to draw the gun and turn it toward the target but at least you can walk without looking like you've been on a horse all day and sit without getting poked, if you know what I mean! Once you move the fabric around a bit, it's quite comfortable! It does make a little noise when you walk and will only hold the smallest of guns. I got my Glock 42 .380 to work but anything bigger would be going places it shouldn't!
Bought it for the wife. It' will definitely accommodate a VERY small single stack weapon well. The wife's preferred carry is the P365 Sig with the 12 round mag, which is slightly too large for this holster. Her smaller single stack .380 works well. Still a decent out when she is wearing a dress. Good quality and fit.
