I've been growing my hair for a year too, but my hair is very fine, so bought a 3/4 hair piece and a ponytail. I've not worn them for work yet, but when I was at a fetish event recently I wore my ponytail and had some fun with another girl. Even though it was securely fastened in, she still managed to pull it off, which made me think that either hair pieces may not be suitable for work, especially (as I've mentioned before) if clients like to run their fingers through my hair. Shame as I love the different looks they give me.
