Another idea for a single-flower look is just to put a daisy, iris, tulip, or lily bud pretty much anywhere. It'd be fun to have maybe a small bouquet of lilies twisting up and around your ankle.
Another fun way to go is with favorite phrases spelled out in other languages, particularly languages which don't use the Roman characters we see every day. Characters and words from Asian languages are very popular, as are Gaelic symbols. There are all kinds of symbols out there that can say exactly what you want them to, though they will have to get that cute guy to come over and talk to you to ask you what they mean if he wants to know about it!
