This perfume went through some name changes before Parfums de Marly settled on Greenley. Its original title was "Sutton," and you can still find pictures of boxes with that label from late 2019 and early 2020. The story goes that another company had something that went by "Sutton" (gee, wonder which one it could be?), and it politely asked PdM to reconsider. Then they road-tested "Epsom," which is an odd one, although there's virtually no evidence of this to be found online, so I don't know how true it is. Eventually they went with the color of the packaging, the safest (and lamest) choice.
My take on Greenley is that it faces a few insurmountable challenges. Its main problem is that it inhabits the Creed price bracket at $355 for 75 ml, and Creed does green better than every other niche brand in existence. Want something fresh, green, clean? Original Vetiver. Want something manly with a perfect grassy/green apple accord? Green Irish Tweed. Looking for an edgier fruity-green? Silver Mountain Water. These frags are expensive, but they're expensive for a reason: they smell miles better than anything in the designer realm, and they're made with top-tier synthetics. For Greenley to stack up, it needs to match or surpass the Creed standard by using equivalently good materials in an equally-great composition. Unfortunately, it falls short. Like, $300 short.
Greenley smells remarkably close to Banana Republic's Grassland, and I suspect the latter is a straight-up clone. Both fragrances are directly predicated on a familiar cast of sweet-green violet-leaf-and-ginger things popularized by Green Valley (1999, another Creed). Both open with a translucent mélange of green apple and citrus, both pop and fizz their way into serene grassy-woody handsoap hearts, and both end up on simple bases of Cashmeran and white musk. Greenley's apple is perkier and its heart is pinier, but it's undeniably a waste of cash. For soapy-green, get Grassland instead.
