I carried a Walther PP for many years. It's about the same size and profile as the Sig 232. Carried it in either an Uncle Mike's IWB nylon holster or an ankle rig (also Unkle Mike's). Most of the nylon holsters from Unkle Mike's are inexpensive (like under $30) - and they are of good quality. In fact, I still have the old rigs that sometimes carry a small revolver. Under $40 for both and 20 years later, they still work fine.
These small pistols are very slim & compact, so comfortable concealment is typically pretty easy in a variety of modes. I'm assuming from your nickname that you are a lady - so why not just use a purse? Preferably something with a long strap you can drape over your neck and carry under an arm. There are some made with quick access pockets specifically for handgun carry. They tend to be a bit more pricy than an Unkle Mike's rig - but then you get something suitable for multiple purposes - with secure & quick access to the weapon - and no one is the wiser that you are carrying.
