Tuckable holsters are great. You can always modify your dress, too.
I wear vests a lot; a good way to class-up an otherwise casual get up of jeans and a sport-shirt, and looks great with a suit. Lets me conceal an IWB holster, tuckable or not, with ease.
I don't carry at work anymore. Changed jobs and now its a no-no.
