Oddly glitzy male with very big gadgets (6)
I believe the answer is:
gizmos
'gadgets' is the definition.
('gizmo' can be a synonym of 'gadget')
'oddly glitzy male with very big' is the wordplay.
'oddly' indicates alternate letters.
'male' becomes 'm' (common abbreviation).
'with' is a charade indicator (letters next to each other).
'very big' becomes 'os' (abbreviation for outsize).
The alternating letters of 'glitzy' are 'giz'.
'giz'+'m'+'os'='GIZMOS'
(Other definitions for gizmos that I've seen before include "Gadgets, contraptions (6)'" , "Useful gadgets" .)
