I like what Ginger said, too. As in , " Ask me about my in-store personal styling services"
I think there has to be some kind of "signage" going on. That lets people warm up to the idea and see some legitimacy (sure, you could have walked in off the bread truck and be impersonating a stylist, but that's less likely!) .
This may be my unfiltered self talking, but I hope there are some kinds of plans for this sort of in-store brand-supported "advertising" to help you-even if you're the one to think some of it up and propose options. If not, I'd have to wonder, what were they thinking? That you'd just constantly be adding, "I'm a personal stylist, you know" all day long?
Because with some signage, you get some walk-by glances. You know, big dept store "boutiques" (meaning the separate brand areas) often have some kind of little promotion or thing going on and it's put on the overhead announcements and cards are handed out and so forth.
Sometimes I feel bombarded by cards being handed out, perfume samples, and I feel free to just shake my head and walk by, but the good thing about it is, it's not personal and carries no commitment but it's a reference. So as you say, someone rushing through to get the wedding present may not be able to stop but would have a card, if they frequent that store.
Also, maybe clarify--will you also be a SA, or you there in only the stylist role and the SA's are there also?
