Judy Blue denim is very stretchy, so most styles fit best when you size down one from your usual department store size. This guide covers how Judy Blue jeans fit, what size to buy, the official Judy Blue size chart with waist and hip measurements, inseam lengths, and shorts sizing. Every product page also lists sizing specific to that style, and our denim is tried on by real women across regular and curvy sizes, so you can order with confidence.
Judy Blue sizing: quick answers
- Do Judy Blue jeans run big or small? Neither. They are very stretchy, so most styles wear best one size down from your department store size.
- Are Judy Blue jeans true to size? Not usually. Most styles fit best one size down. If you carry weight in your midsection or have wider hips, you may prefer your true department store size for a roomier waist.
- What size Judy Blue jeans should I buy? Start one size down from your department store size, check the waist and hip chart below, then follow the recommendation on the product page.
- Do curvy sizes fit the same way? Yes. Curvy sizes 14W to 24W generally size down one, then follow the size guide.
New to boutique denim sizing?
Boutique denim uses odd sizes. Your true odd size is simply one number down from your true even size. For example, if you are a women's 10, your true odd size is a 9. That is the same size, not a size down. From your true odd size, you then follow the size-down-one advice above.

How to measure
Waist: measure around your natural waistline, keeping the tape comfortably loose.
Hips: measure around the fullest part of your hips.
Inseam: measure along the inside leg, from the crotch seam to the bottom hem.
Inseam and length
Most Judy Blue styles come in a single inseam, so length is worth checking on each product page, where we list the actual inseam. Some styles, like our Judy Blue Cali bootcut, come in short, regular, and long inseams so you can skip the tailor. Petite? Shop short inseam jeans at 30 inches and under. Tall? Shop long inseam jeans at 33 inches and up.
Judy Blue shorts sizing
Judy Blue shorts use the same sizes as Judy Blue jeans, so the size chart above applies. Most Judy Blue shorts are very stretchy and fit best one size down from your department store size. Longer Bermuda styles often fit true to size, so check the recommendation on each product page. Shop all denim shorts.

Frequently asked questions
Do Judy Blue jeans run big or small?
Neither. Judy Blue denim is very stretchy, so most styles wear best a size down from your usual department store size rather than running large. Always follow the per-style recommendation on the product page.
Are Judy Blue jeans true to size?
Most styles are not worn true to size. Because the denim is very stretchy, most shoppers size down one. Some styles, and shoppers with wider hips or more weight in the midsection, do better in their true department store size, so check each product page.
What size is a Judy Blue 9, 11, 13 or 15?
Judy Blue sizes pair a women's size with a waist number: 9 is (29), 11 is (30), 13 is (31) and 15 is (32). See the size chart above for the waist and hip measurements for each one.
What size should curvy shoppers order?
Curvy sizes 14W to 24W generally size down one, then follow the size guide. If you carry wider hips, you may prefer to stay true to your department store size for a roomier fit.
How do I know the length will work?
We list the actual inseam on every product page and sort styles by length. Styles offered in multiple inseams, like the Cali bootcut, make it easy to match your height.
