Shoppers looking for a tight sweater want women's knitwear that follows the torso without bagging at the waist or stretching out after a few wears.
- Match bust, waist, and sleeve measurements to your body instead of relying on S-M-L alone.
- Note knit gauge and fiber stretch so ribbing recovers after you raise your arms.
- Check length at the hip if you plan to tuck it or wear it over high-rise bottoms.
Use those numbers on the listing to choose a close fit that still lets you move.
