Frequently Asked Questions
Are these cardigans true to size?
Sizing is mixed across customer feedback. Many find the listed sizes fit well, but several shoppers recommend checking measurements and considering an upsize if you prefer a looser, layered look. Review the size chart before ordering.
Will a cropped cardigan keep me warm in fall?
Cropped, lightweight cardigans are best for mild fall mornings and provide a comfortable extra layer without overheating. For colder temperatures you’ll want a heavier knit or an additional layer.
How do I care for these lightweight cardigans?
Follow the care label, but most lightweight blends do well with gentle machine wash or hand wash in cold water and flat drying to preserve shape and reduce pilling. Avoid high-heat drying which can affect fit and softness.
