Understanding Knitwear Fit


Fit is the foundation of comfortable and flattering knitwear. A sweater that fits well will keep you warm and look stylish without feeling bulky or restrictive.


  • Know your measurements: Use a tape measure to check your chest, waist, and arm length. Compare these with the sizing chart of the brand.

  • Consider layering: If you plan to wear shirts or t-shirts underneath, choose a slightly looser fit.

  • Try different styles: Crew necks, V-necks, and turtlenecks fit differently around the neck and shoulders. Pick what feels comfortable and suits your face shape.

  • Check sleeve length: Sleeves should end just past your wrist bone. Too short or too long sleeves can affect warmth and appearance.

  • Look for stretch: Knitwear with a bit of elasticity adapts better to your body shape and movements.


A well-fitted sweater enhances your silhouette and maximizes warmth by trapping heat close to your body.


Choosing the Right Fabrics: Wool vs Acrylic and More


Fabric choice affects warmth, durability, and care. Here’s a breakdown of popular knitwear fabrics:


Wool


Wool is a classic winter fabric known for its excellent insulation and breathability.


  • Merino wool: Soft, fine, and less itchy. Ideal for sensitive skin.

  • Cashmere: Luxuriously soft and warm but more delicate and expensive.

  • Lambswool: Thicker and warmer, great for chunky sweaters.

  • Wool naturally repels water and dries quickly, making it practical for cold, damp climates.


Acrylic


Acrylic is a synthetic fiber often used as a wool alternative.


  • Lightweight and affordable

  • Easy to care for and machine washable

  • Less breathable than wool, which can cause overheating or sweating

  • Tends to pill over time, reducing the garment’s appearance


Blends


Many knitwear pieces combine wool and acrylic or other fibers to balance warmth, softness, and durability.


  • Blends can reduce itchiness and improve stretch

  • Often more affordable than pure wool

  • Check the label for fiber percentages to understand care needs


Other Fabrics


  • Cotton: Breathable but less warm, better for mild winters or layering.

  • Alpaca: Warm, soft, and hypoallergenic, but pricier.

  • Synthetic blends: Often used for sports knitwear, offering moisture-wicking and durability.


How to Care for Your Knitwear


Proper care extends the life of your sweaters and keeps them looking fresh.


  • Read care labels: Follow manufacturer instructions for washing and drying.

  • Hand wash or gentle cycle: Wool and delicate fabrics benefit from hand washing or machine washing on a wool cycle.

  • Use mild detergent: Avoid harsh chemicals that damage fibers.

  • Dry flat: Lay sweaters on a towel to dry to prevent stretching.

  • Store properly: Fold knitwear instead of hanging to maintain shape.

  • Remove pills gently: Use a fabric shaver or comb to keep sweaters smooth.


Finding the Best Knitwear for Winter in the UK


The UK’s cold, damp winters require knitwear that balances warmth and comfort.


  • Look for wool-rich sweaters for insulation and moisture resistance.

  • Choose styles with ribbed cuffs and hems to keep cold air out.

  • Consider layering options like cardigans or zip-up knits for versatility.

  • Shop from brands known for quality knitwear and ethical sourcing.

  • Check customer reviews for fit and fabric performance in real UK weather.
