Business Nipples

I've always had perky nips that show through my shirts. I'm famous for them.

It's not been a problem really. At my last job I wore scrubs, so a heavy t-shirt and heavy scrubs meant no show nips.

Now, I'm back to business casual and even with an undershirt and a work shirt (especially a polo) - NIPS ALL DAY.

Any creative solutions or options for me?
