I have a hibiscus flower on my right shoulder blade and am getting another one today. where is a good place?

my hibiscus flower is the only tattoo i have. I'm getting my second one today. My favorite flower is a lily, but i'm afraid it won't look right if i put a lily on my left shoulder. My tattoo after this one is all picked out and ready so the tops of my feet are taken. I work in a Vet clinic so the tattoo has to be fairly easily hidden. No tramp stamp, and no arms or hands. any suggestions?
