Office social gatherings, annual meetings, office picnics encourage team building and camaraderie. A function at the office calls for saris that are modest, formal with an element or two that says something about you. So maybe you could opt for stiff fabrics with a bit of starch with light work on the pallu or go for colours like yellow or maroon with the pallu in a classic pin up style that suggests formal relations but are attractive enough to make it a bit different from what you might wear everyday to your office. The darker the colours, the more formal the look. So if you can't play with colours, pay attention to the borders. Go with gold, bright red and blue, violet, orange coloured borders. Avoid being too traditional and too glamourous- large bindis, heavy necklaces, bright colours in silks and back-less blouses are inappropriate. Instead play with long sleeves, mid sleeves and thick straps in black, dull gold, bottle green or white. You can even don a blazer, or a stylish jacket with the saree for a modern look. Dress according to the event- which might be formal, semi-formal, festive to even casual. Get along with and know people outside the confines of work at an office function in a smart and dapper sari.
