dateless
Solo at prom
Dateless means without a date—either lacking a companion for a social event She arrived at the prom dateless or having no recorded date a dateless manuscript.
The second sense extends to things so old or timeless they transcend dating: dateless customs, dateless beauty.
The "without a companion" sense is now more common in everyday speech.
