Theres no secret in fragrances. And I don't have a signature fragrance. I don't think most guys on here do, anyways.
If someone ever asks me....and it has been forever since someone did....I will tell them. I'll tell them more, actually "...by the way, if you want a really well made scent, check out..."
And if someone prances around with my favorite scent(s) and oversprays them...if that happens...I will deal with them.
