The Dutch police union has received dozens of official complaints from policewomen about their new uniform blouse which they say is see-through.

The officers feel "uneasy" and "closely watched" while wearing the new garment, police union chairman Hans van Duijn told Monday's edition of the Algemeen Dagblad newspaper.

Van Duijn suggested that police start issuing official undershirts to tackle the see-through problem.

This is not the first time the new blouse has sparked complaints. Earlier gold buttons on the breast pockets were replaced by more subdued white buttons because female officers complained the flashy gold drew too much attention to their chest.
