I've not smelled Green Irish Tweed, but AMR's website says Trafalgar is inspired by GIT. It's extremely fresh, floral and as such, quite unisex. A perfect spring/summer scent where the Violet Leaf really pops. It reminds me of clothing that has just been freshly laundered. This scent is most definitely office safe and can we worn at any time of year, in any environment. It's a bargain price here at allbeauty. I also have Holborn which is inspired by Allure Homme Sport. That's also very good and a great buy.
