Calvin Klein Women's Size Chart

Use this women size chart to compare your measurements against Calvin Klein's official sizing. Each table shows body measurements and international conversions.
Fit Notes
Calvin Klein's men's underwear is the reference in the category — the numeric waist size is drafted true and the elastic recovers reliably wash after wash, which is why the brand keeps its category leadership. Ready-to-wear runs on the slim side of the American block: dress shirts are cut with a defined taper (Slim Fit is aggressive), and the Extreme Slim is only viable on a genuinely lean build. Women's dresses skew short in the torso, particularly on the sheath and slip cuts, and CK Sport uses a different, more athletic block than the mainline. The Calvin Klein Jeans capsule runs one full size smaller than mainline CK on tops.
Common Sizing Mistakes
The most common return is a Slim Fit dress shirt bought by someone who wears a US Regular Fit medium elsewhere — CK Slim is a full step tighter than the industry average and is not comparable to a generic Slim from a mall brand. On women's jeans, buyers often ignore that the current CK Jeans denim uses stretch cotton and holds its size, unlike the older rigid runs the label used to sell. A third pitfall: CK men's underwear multipacks occasionally include a mix of Modern Cotton and Cotton Stretch waistbands that fit slightly differently at the same waist number.
How Calvin Klein Compares
Against Hugo Boss, Calvin Klein Slim Fit sits about the same in the chest but is longer in the sleeve, and the CK collar tends to be a hair softer at the same neck. Against Tommy Hilfiger, CK Slim is meaningfully tighter through the waist than Tommy's Slim of the same nominal size. Against Michael Kors ready-to-wear, CK women's dresses run a size smaller and shorter in the length.
