I highly doubt your stylist cares one way or the other, but many men have their ears pierced, so wear simple non-gendered studs if you are concerned.
My wax technician sees me in panties every three weeks, and some are more fem then others, but at my last appointment she asked if I was doing anything special on the up coming weekend and I said I was getting dressed up. She assumed I meant suit and tie, but I said no, I am will be wearing a dress. She just said, cool, and continued ripping the hair out of my leg follicles. She knows I wear nail polish at times, so I doubt she was the least surprised.
