Style 1 (left) is what I call "the saree suit style. It's when the pallu/achal is draped over in front.
Style 2 (middle) is the traditional Indian style saree. Here you have the pallu/achal draped going back over your shoulder.
Style 3 (right) is the traditional Bengali style. Famously seen in the Bollywood film "devdas" here the pleated saree in front of the leg are not placed normally like the other 2 styles. The pallu/achal is taken over and under on the opposit side.
The saree is from Diya online £35 (est) and it's my first saree that I have owned and not given to me.
