People having more than one perfume and changing them according to occasions would find this interesting I guess
Maybe knowing who's choosing the perfumes will give more confidence and credibility
Good luck !
I just don't see people paying for someone to pick out fragrance for them. It's very personal and people only like very small percentage of perfumes they try. I personally dislike over 90% of perfumes I try and since this isn't a cheap product that arrives once a month that would mean I'd be paying 10x+ and waiting on average for about a year to find something I like.
Perfumes just seem to be too subjective to leave the selection to somebody else. Good luck though.
