I've a few which have been my faves for decades, since I first bought them Duty Free, & I just keep buying them, as they suit my skin admirably!
The old story 'when you're on a good thing, stick to it' certainly applies to my perfume purchases'!
'L'Air du Temps'
'Madame Rochas'
'Arpege'
Have of recent times bought some '4711', & their Refresher Sheets are wonderful!
Yardley 'Lavender', have re-visited, along with its' Talc.
I'm a great believer in one has to 'smell nice' when going out, even if 'just shopping'!
