Given his complexion and hair (what’s left of it), I’d suggest dark purple for the stilettos, matching hosiery, a gown with dark material lower and a lighter, bluer upper portion (not deep cuts, please). As for the earrings, definitely platinum alloy, and if stones/bling is needed a mixture of blue diamonds and blue star sapphire. Keep the hair silver.

Probably will end up looking like Barbara Bush.
