Salwar Suit or Saree for Ashtami Anjali?
Pushpanjali on Ashtami morning is the one moment of the six days where what you are wearing has to survive something specific: a long wait, a packed floor, bare feet, and both hands occupied with flowers.
The saree-versus-suit argument usually gets decided on tradition. It is more useful to decide it on those four constraints.
The case for the saree
It is what the morning looks like, and there is no arguing with that. A cotton or Tussar saree in red and white, worn in the atpoure style with the pallu over the left shoulder and the keys knotted in, is the image of Ashtami morning for a reason.
The practical version: a light cotton or Kota saree, not silk. Silk on a crowded floor at eight in the morning is a mistake you make once. See cotton and linen sarees and Kota sarees.
The case for the suit
Both hands are going to be full of flowers. You will be pressed against strangers. You may be holding a child. A saree needs a hand free roughly every ninety seconds and an anjali does not give you one.
A straight-cut suit or an Anarkali in cotton silk solves all of that and, in the right colour, looks entirely correct. Nobody at a pandal has ever thought less of a well-cut suit. See salwar suits and Anarkalis.
What people actually get wrong
Not the garment — the fabric. Georgette and chiffon in a morning crowd wrinkle and cling within twenty minutes. Heavy zari catches on other people. Anything sheer needs lining you will not have thought about at seven in the morning.
Pick cotton, cotton-silk, chanderi or light Tussar in either format and the choice between them stops mattering.
The compromise
Suit for the morning anjali, saree for the evening. That is what most of Kolkata does and it is the right answer. The six-day plan splits the days that way throughout, and the festive collection carries both sides of it.
