How to Wash Girl Sweaters Without Shrinking or Pilling

Quick answer

Turn sweaters inside out, wash in cold water on a gentle cycle with a mesh bag, and lay flat to dry. Skip the dryer and fabric softener—both cause shrinking and pilling. For wool, use a no-rinse wool wash and handle as little as possible.

Why sweaters shrink and pill in the wash

Heat and agitation are the two biggest enemies of knitwear. Hot water makes natural fibers contract, and the tumbling motion of a dryer or heavy cycle rubs fibers together until they ball up into pills. Fabric softener coats fibers and makes them stick, which actually speeds up pilling.

Cotton-spandex blends, like those in many Tea Collection dresses and skorts, are more forgiving but can still lose shape if washed in hot water. The same gentle approach works for both natural and blended knits.

Sort and prep before washing

Separate sweaters from heavy items like jeans or towels, which can abrade delicate knits. Close zippers and hooks on other garments to prevent snags. Turn each sweater inside out and fasten buttons or snaps to keep the shape.

Check the care label first. If it says dry clean only, follow that. For washable sweaters, a mesh laundry bag is your best friend—it keeps the sweater from stretching or catching on other clothes.

Choose the right detergent and cycle

Use a mild, pH-neutral detergent or a dedicated wool wash. Avoid detergents with bleach, enzymes, or optical brighteners, which can fade colors and break down fibers. For wool, a no-rinse formula lets you skip the agitation of rinsing.

Set your machine to cold water and the gentlest cycle available—usually labeled delicate, hand wash, or wool. If your machine has a spin speed setting, choose low. High spin speeds can stretch sweaters out of shape.

Drying without a dryer

Never put a sweater in the dryer unless the care label explicitly allows it. Heat is the fastest way to shrink wool and cause pilling. Instead, gently press water out with a clean towel—do not wring or twist.

Lay the sweater flat on a drying rack or a towel, reshaping it to its original dimensions. Avoid hanging, which can stretch shoulders and lengthen the body. Keep it away from direct sunlight and radiators, which can fade colors.

Fixing accidental shrinkage

If a wool sweater shrinks slightly, you can sometimes relax the fibers by soaking it in cool water with a little hair conditioner or wool wash for 15 minutes. Gently stretch it back to shape and lay flat to dry. This works best on minor shrinkage, not felted wool.

For cotton blends, a cool soak and gentle stretching can help, but prevention is far easier. Always check the label and when in doubt, hand wash.

Step-by-step sweater washing routine

1. Check the care label: Look for the wash symbol and fiber content. If it says dry clean only, stop here. For washable sweaters, note the recommended water temperature. Common mistake: assuming all sweaters can be machine washed. When in doubt, hand wash.
2. Prep the sweater: Turn it inside out, close any buttons or snaps, and place it in a mesh laundry bag. This prevents snags and reduces friction. Checkpoint: the sweater should lie flat inside the bag without bunching.
3. Wash on cold and gentle: Use a mild detergent and select a delicate or wool cycle with cold water and low spin. If hand washing, gently squeeze suds through the sweater without rubbing. Common mistake: using fabric softener. It causes pilling and reduces absorbency.
4. Remove excess water: Lay the sweater on a clean towel, roll it up, and press gently to absorb water. Never wring or twist. Checkpoint: the sweater should feel damp, not dripping.
5. Dry flat and reshape: Place the sweater on a drying rack or dry towel, smoothing it to its original dimensions. Keep it out of direct sun and away from heat sources. Common mistake: hanging a wet sweater, which stretches the shoulders and hem.
6. Store folded: Once completely dry, fold sweaters and store them flat. Hanging can cause shoulder bumps and stretching over time. Next step: for long-term storage, add a cedar block or lavender sachet to deter moths.

Tea Collection pieces that benefit from gentle care

• Twirl Skort: Twirl Skort is crafted from a cozy and stretchy cotton-spandex blend with a comfy elastic waistband and fitted shorts. The spandex helps the skort keep its shape, but hot water and high heat can still break down elasticity over time. Cold washing and air drying protect the stretch.
• Twist Back Ballet Dress: Twist Back Ballet Dress is made from soft cotton-spandex jersey with a boat neckline, short sleeves, full circle skirt, and a twist cutout at the back. The twist cutout and circle skirt can lose their shape if washed with heavy items or dried on high heat. Use a mesh bag and lay flat to dry.
