Gaudy description of nails? (5)

I believe the answer is:

tacky

I believe this is a double definition.

'gaudy' is the first definition.
(I know that gaudy can be written as tacky)

'description of nails?' is the second definition.
(a tack is a nail or pin)

(Other definitions for tacky that I've seen before include "In poor taste; not yet dry" , "Vulgar - viscous" , "Sticky; of poor quality" , "Gaudy" , "not quite dried?" .)

I've seen this clue in The Sun and The Times.
