Fit of a garment is a personal choice. You may like your sweaters skin tight (and have the figure to pull it off), but others feel they need a bit of "wiggle room" to be comfortable.
Knit it Now Sizing charts indicate the BODY MEASURMENTS that are used to size our garments.
The pattern sizes and dimensions listed are garment FINISHED MEASUREMENTS. The amount of ease is up to you.
We recommend measuring a garment you wear and copy those measurements.
