Regularly sells uniform for cricket team (6)
I believe the answer is:
eleven
'cricket team' is the definition.
(a cricket team has eleven players)
'regularly sells uniform' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'uniform' becomes 'even' (I've seen this before).
The alternate letters of 'sells' are 'el'.
'el'+'even'='ELEVEN'
'for' acts as a link.
(Other definitions for eleven that I've seen before include "Time for the mid-morning tea break?" , "Number of pipers piping" , "Number on a soccer team" , "football team, for example" , "Late" .)
