A snub in your pocket pretty much looks like a snub in your pocket.
I think that depends on what you wear. I've always worn relaxed fit pants, and a snub in my pocket looks like a wallet. My guess is that 1 in 500 people wonder if it's something else. I do have a few "office" pants that don't conceal it as well, so I don't wear them if I plan to pocket carry. It's the same as concealing a firearm in any other way; you dress accordingly.
