The Ultimate Guide to Finding Your Perfect Judy Blue Jeans Size
Finding a pair of jeans that fits like a glove can feel like a fashion miracle. If you’ve heard the buzz about Judy Blue jeans, you know they are famous for their "magic" 4-way stretch and incredible recovery. But because they are so stretchy, the #1 mistake shoppers make is buying their usual size only to find them bagging out by lunch.
To help you get that perfect fit, we’ve broken down the "Judy Blue Math" so you can shop with confidence.
________________________________________________________________________________________________
Step 1: Find Your "True" Starting Size
Before you can size down, you need to know where you're starting. Judy Blue uses odd numbering (0–15) for regular sizes and W-numbering (14W–24W) for plus sizes.
-
Regular Sizes (0–15): Take your typical even department store size and subtract one.
- Example: If you usually wear a size 10, your starting Judy Blue size is a 9.
-
Plus Sizes (14W–24W): Most plus-size customers find their "true" fit by staying with their standard department store size.
- Note: A size 15 is considered a regular cut, while a 14W is a plus cut. The 14W will have more room in the hips and thighs even if the waist measurement is similar.
Step 2: When to Size Down
The general rule for Judy Blue is to size down one from your starting size, but your body shape and desired fit play a huge role.
- The "One Size Down" Rule: Because of the high stretch content, most women find the best fit by going down one full size from their "true" size.
-
The "Locked and Loaded" Fit: If you prefer your jeans to feel like a second skin (often called the "booty pop" look), you can size down two from your starting even size.
- Warning: Only do this if you don't carry much weight in your midsection, as the waistband may become too tight.
Step 3: Sizing by Style
Different cuts require different sizing strategies. Here’s how to navigate the most popular styles:
- Boyfriend & Relaxed Fit: These are designed to be roomier. To keep them from looking sloppy, always size down at least one.
- Skinny & Slim Fit: These styles are meant to be snug. Sizing down ensures they hug your curves without sagging.
- Tummy Control Styles: These feature a secret mesh panel to smooth the midsection. Most people stay with their typical Judy Blue size for comfort, but you can size down for extra compression.
- Flares & Bootcut: Because these often have a lot of fabric in the leg, a well-fitted waist is key. If you have slimmer hips, sizing down is recommended.
- Rigid Magic (Non-Stretch): Be careful! Styles with a "rigid" front (100% cotton front) have significantly less stretch. It is often best to stay true to your size or only size down if you are between sizes.

Pro-Tip for Longevity
To keep your Judy Blues in top shape, never put them in the dryer. The high heat can damage the spandex fibers (the "stretch"), leading to lost recovery over time. Wash them in cold water and hang them to dry for a fit that lasts for years.
