"Age ain't nothin' but a number..."
I would recommend the following:
J.C Brosseau Ombre Rose L'Original - soft rose powdery very similar to L'Aimant
Dolce & Gabbana (Red cap) - Modern Aldehydic Floral
Caron Infini - Classic Aldehydic Floral
Avon Topaz - Classic Aldehydic Floral, discontinued but can still be sourced on line.
Crown Perfumery Marechale - Discontinued but still available sometimes online.
Caron L'Heure Bleue - different floral but still classic, elegant and powdery in drydown
Caron Nuit de Noel - different floral but still classic, elegant and powdery in drydown
Lanvin Arpege - 'Warmer' and slightly more elegant. more orris than rose. smooth.
as well as the ubiquitous Chanel No. 5 which is much more 'severe' and aloof than the wonderfully optimistic romantic L'Aimant.
Hope these help. Good luck!!
