How to choose Calvin Klein underwear

Related: Women’s Underwear Size Guide Chart And Sizing Guide, How to Measure Your Body for Clothing Sizes

Choosing CK underwear that fits is quite easy. The first step is to get your measurements, preferably inches, because most CK underwear charts are denoted in inches. You can take your measurements at home or have an experienced person help you. However, when measuring your waist, underbust for band size and overbust, an ordinary ruler may be ineffective, especially for the cup size.

Once you have your measurements, the second step is to look through the charts for the underwear you want to buy. Your measurement would correlate with one of the sizes indicated on the chart. For example, a woman with 25 inches waist measurements and 35 inches hip measurements would use XS panty size. If you find it difficult to get your size due to a larger range of measurements, use the plus-size Calvin Klein Big & tall size charts. These charts are specifically channeled to provide size guides for customers using the plus sizes.
