How discrete is an inner bicep tattoo?

I know its a rather sensitive area, but I'm not worried about pain. Pain is temporary but tattoos are forever. The design I have picked is a very traditional rose and swallow. I don't have a "career" locked in yet, I've still got plenty of schooling. I see all these professionals with outer forearm tattoos and such, so I don't think it'd be that big of a deal anyway, but I'm not looking to ruin my chances at a good workplace.

Many of the people I've seen with inner bicep tattoos can hide them pretty well by just wearing a longer short sleeved shirt. I was wondering what your opinions are on the discrete-ness of an inner bicep tattoo?

I do want this tattoo somewhere that can be shown off when I want it to be, yet can be hidden when necessary. I also don't want it in a place that I would have to wear a bikini for it to be visible.
