Sadly Gucci pour homme, my favourite smell on DH ever, has been discontinued and any bottles cropping up on eBay etc are out of my price range. Similarly Dermot O'Leary Vetiver & Cedarwood -another fanny gallop inducing favourite of mine- is now no longer available. 
I'm going shopping soon to try to find an aftershave for DH. He is very easy going and although Gucci was his favourite he likes almost everything (even Joop ) so all that really matters is that I like it and find it as 'sexy smelling' as the aforementioned. So I'm trying to work out what other fragrances I might like. Gucci is a 'woody chypre' apparently, I don't know what the Dermot one is classed as, but another smell I really like is Bayliss & Harding Oud, Cedar and Amber, oddly, so maybe that helps?
I find a lot of fragrances really unpleasant and get headaches from them. Ones we've tried before and rejected: Gucci Guilty (sort of ok, tolerable); Eau Sauvage (sickly, headache); Bentley Absolute (read that it smells like Gucci but DOES NOT, vom vom vom, think it might smell of an earlier similar named Gucci that was discontinued in 2003). My DSs wear Joop and Versace Blue Jeans and I cannot bear the smell. I've never smelled a Tom Ford I like and I've sniffed a lot of them. We tried a Gucci dupe from somewhere and that was useless too.
I don't want to blindly go sniffing a load of aftershaves because i know i will end up feeling nauseous, so any pointers to likely aftershaves I can try out on our shopping trip would be very welcome please 🙏
