If you love quality underwear, you either have some Calvin Klein or are considering buying. But do Calvin Kelin underwear shrink, last long, or run small or big?

Calvin Klein underwear shrinks when washed and dried in a high-temperature setting. You can also shrink the underwear by soaking them in boiling water for 3 – 5 minutes.

This article discusses essential points about Calvin Klein underwear so that you can discover how to take good care of the underwear.

Does Calvin Klein Underwear Shrink

Shrinking in underwear entails how underwear changes in measurement during the washing process.

There are three main factors in determining whether Calvin Klein underwear can shrink. The factors are fabric used to make the underwear, additional moisture, and heat and agitation in the washing machine.

For the type of fabric, natural fabrics shrink faster than synthetic fabric. Therefore, when underwear is made of natural fabric such as cotton, linen, or silk, there is a high chance that the underwear will shrink in the wash.

If the underwear is made of synthetic fabric like polyester or nylon, the underwear is less likely to shrink since synthetic fabrics are resistant to shrinking.

For additional moisture, natural fabrics such as cotton and linen are susceptible to relaxation shrinkage. As the fibers absorb water, their fibers swell, resulting in the overall size of the underwear to reduce.

For heat and agitation, it involves ensuring agitation in the washer and dryer combined with high temperatures. The conditions cause shrinkage in garments they are washed and dried in high temperatures.

Calvin Klein has 100% cotton underwear, while the Micro Modal collection is made from 90% modal and 10% lycra elastane.

Calvin Klein underwear made from 100% cotton will shrink in the washer if washed with hot water. The Micro Modal collection will not shrink in the wash since modal and lycra elastane is synthetic fabrics resistant to shrinking.

To avoid your Calvin Klein underwear shrinking, always ensure that you wash the underwear in the right water setting. The water temperature in the washer should never exceed 130 Fahrenheit since cotton fibers start to shrink at any temperature above 130 Fahrenheit.

Whenever you wash your Calving Klein underwear, ensure you wash the underwear in cotton or a delicate wash cycle.

How To Shrink Calvin Klein Underwear

When shrinking Calvin Kelin underwear, the underwear made with 100% cotton will be easy to shrink. The modal collection will be challenging to shrink since the underwear is made from natural fabrics resistant to shrinking.

With determination and persistence, the modal collection of Calvin Klein underwear can shrink between 3 – 5%. The 100% cotton underwear can shrink up to 20% when the underwear is not pre-shrunk.

Older Calvin Kelin underwear that has been worn and washed for some time will be easier to shrink than the new underwear. The pre-shrunk feature in older underwear will have become less effective, thus making it easy to shrink the underwear.

To shrink Calvin Kelin underwear, you can wash the underwear with hot water and dry it in hot temperatures. The other method to shrink the underwear involves boiling it in hot water.

If you have new Calvin Kelin underwear that you have not worn and are in good condition, you should consider returning the underwear and getting your correct size instead of shrinking them.

If you have already worn the underwear, you cannot return them as the store you bought them from won’t accept the return. Shrinking the underwear will be your best option in this case.
