Not bad at all! My husband has a flashbang holster: his underpants!http://www.flashbangholster.com/Flashbang_Holster/Welcome.html
you know..this might not be half bad.
Thanks for mentioning the crossbreed. I found them on Youtube with a very slim young lady demonstrating different clothes and just how concealed this holster is. Very impressive. I may be opting for a different conceal gun, money willing, very shortly and will likely invest in a Crossbreed.I have a friend who bought one. She let me take it home and try it out after she decided it was too uncomfortable. Like her, I found it to be really uncomfortable -- it poked me all the time. Plus, the added weight on my bra straps really makes my shoulders, neck and upper back hurt.
I have found that an IWB crossbreed holster to be a lot more comfortable. Plus, I can hide my LC9 in the IWB holster better. Largest I could hide in the flashbang was my LCP.
