Not possible to make out? (13)

I believe the answer is:

unfashionable

This clue is a double definition.

'not possible to make' is the first definition.
(not able to be fashioned or made)

'out?' is the second definition.
('unfashionable' can be similar in meaning to 'out')

(Other definitions for unfashionable that I've seen before include "Not popular" , "Not chic" .)

I've seen this clue in The Times.
