If you are new to paper patterns, one of these is considerably more forgiving.
Start with a blouse. It uses less fabric, so a mistake costs less, and it has fewer pieces to keep square to the grain.
A chudi is a bigger commitment: the top, the pant and the flair all have to agree with each other, and an error in the seat measurement shows up in three places at once.
Once a blouse fits you off our pattern, the same upper chest figure carries into the chudi top, so the second garment is far quicker than the first.
