I second Wirarpa boxers, they're incredibly good and I ended up ditching out all of my sloggis et al in favour of them.
In all honesty, with the exception of jeans and underwear everything I buy is mens including deodorant and perfume. I prefer wood/leather/oud scents to anything citrus or floral.
Some particularly good buys in my opinion (im just over 5'8 for reference)
Mens M&S autograph long sleeved vests pure supima - make really great long sleeved t shirts - quite close fitted, really soft, wash great and are nice and relaxed with jeans. Or they do short sleeves if you prefer that.
Reiss Alexander garment dyed hoodies - slightly oversized so size down - wash well and are soooo soft and comfortable.
Ralph Lauren lounge pants / waffle tops - had mine years that I use as pjs.
Theres an American brand called True Classic that does T-shirts and joggers etc. Theyre designed to be fitted around the chest and arms with some room for the belly on men, BUT they work remarkably well on the female form because they look good on the boobs and arms but also accommodate hips.
Plus theyve always got a sale on and its free duty paid delivery with everything. They sell single items but also packs of 6 v necks etc etc.
Literally all mens sneakers outlast women's ones.
Mens scent - The Penhaligons trade routes are all unisex but none of them are overly sweet or flowery which I like. Quite spicy outdo amber etc etc.
Mens deoderant - Ilex from amazon, natural deodorant - I like the spiced patchouli one because it doesnt actually smell like patchouli. Smells more like spices and warm weather if that makes sense. Like a souk in Marrakech but without the sweaty part 😂
But! My greatest discovery so far is Baylis & Harding Goodness Oud Cedar and Amber shower gel. It's all essential oil based, smells blooming amazing and the scent stays. I get it from amazon at 17 quid for 3 half litre bottles. I think it's unisex but packaged to appeal to men.
