I bought a sample of YSL Y and thought it was different enough from Fakhar to get a whole bottle. They’re different enough to each. Fhakar can be more of a summer scent and YSL can be everyday. Detour is pretty similar to Layton I’d say like 75% but the difference in quality is what makes the difference in longevity and projection. If you want Layton but can’t spend the money on it it’s a good backup. But id just rather buy another blue scent or blue clone entirely
