Frequently Asked Questions
Will these cardigans add bulk over a sundress?
No—these picks emphasize lightweight, breathable knits and longline drapes that skim rather than bunch. Choose a size that follows your natural shoulder line; oversized options will feel airier but can look boxy if too large.
How should I care for a lightweight knit to keep it soft?
Follow the care label, but generally use a gentle machine cycle or hand wash, dry flat to preserve shape, and avoid high heat in the dryer. Many of these GRACE KARIN styles soften after the first few washes—washing in a mesh bag helps prevent snags.
What length is best for layering with short sundresses?
A longline cardigan that covers the hips is flattering with short sundresses because it balances proportions and provides more coverage. If you’re petite, look for a slightly shorter longline or a cardigan labeled as 'petite' to avoid overwhelming your frame.
