Just when we had got used to the pink polo shirts, the Wexford politician was sporting a tight-fitting top with plunging neckline which he teamed with washed out combat pants and his trusty boots.
The deputy's choice of clothing - along with his curly platinum blond hair - has rarely left his colleagues in the Houses of the Oireachtas tickled pink.
And this latest bizarre choice will have many fashionistas shouting 'sack the stylist'.
The daring cowl-neck jersey top is often favoured by much younger, hipster males from Scandinavia -- who always wear them with a white or coloured t-shirt underneath.
But this deep dip in the charcoal top leaves little to the imagination, although it must be said it takes a brave man to be wearing a top like that on a cold and rainy November evening.
Mick often favours pink shirts, brightly coloured airtex t-shirts or tight tank tops, all teamed with washed out jeans or chinos.
And it appears Mick could be modelling his outfits for a little while longer as the proposal to overhaul the Dail dress code has been shelved.
The Committee on Procedures and Privileges discussed the proposal yesterday but it has been parked following a legal question over the ability of the Ceann Comhairle or Oireachtas Committees to sanction members.
The Committee called for business attire including tailored jackets, trousers and collared shirts for men, and a suit, a jacket and trousers or skirt with a shirt for women.
