Understanding the 3 Justice Fit Profiles
Justice designs apparel exclusively for growing girls. Here is how our three distinct patterns differ in cut, ease, and proportions.
Regular Fit
Engineered for standard tween proportions with balanced chest, waist, and hip ratios. Follows standard American youth sizing with modern trendy drops on hoodies and tees.
- ✓ True to standard youth age brackets
- ✓ Tops have modern relaxed shoulder drop
- ✓ Pants include hidden waist elastic buttons
Slim Fit (S)
Created for slender, tall tweens whose pants fall down in standard sizes. We take approximately 2 full inches off the waistband and hips while preserving complete standard inseam length.
- ✓ Exactly 2 inches narrower at waist & seat
- ✓ Full standard leg inseam (never high-water)
- ✓ Eliminates bunched-up belt buckle fabric
Plus Fit (P)
Dedicated pattern grading for curvier hips, fuller chests, and athletic builds. Adds 2 to 3 inches of room through torso and thigh circumferences with proportional non-dragging hems.
- ✓ +2" to +3" extra room across chest & hips
- ✓ Relaxed armholes that don't pinch or bind
- ✓ Inseam graded so pants never drag on shoes

How to Measure Her at Home (Step by Step)
Use a flexible fabric tailor's measuring tape. Keep the tape comfortably snug against her undergarments without squeezing.
Height
Have her stand barefoot with heels, back, and head flat against an even wall. Place a flat ruler level on top of her head and mark the wall, measuring down to the floor.
Chest / Bust
With her arms resting naturally at her sides, wrap the tape measure under the armpits across the fullest part of the chest. Ensure tape is completely level across her back.
Natural Waist
Locate the narrowest part of her torso (usually 1 inch above her belly button). Wrap the tape measure around this natural crease, keeping one finger behind the tape.
Hips / Seat
Have her stand with feet together. Wrap the measuring tape around the widest, fullest point of her hips and rear seat, keeping the tape parallel to the floor.
How Justice Sizes Behave Across Categories
Different garments are engineered with distinct fabric elasticity and ease tolerances.
Graphic & Boxy Tees
Justice tees are designed with a trendy, modern relaxed shoulder drop. They are not tight baby-tees. Cotton blends experience minimal shrinkage when washed cold.
Fleece Hoodies & Pullovers
Engineered with generous room through the body and ribbed wrist cuffs that stay pushed up easily. Cut long enough to comfortably pair with high-waisted leggings.
Tech Pocket & Flare Leggings
Crafted from premium 88% polyester / 12% spandex active jersey with four-way stretch recovery. Designed to hug the body snugly without rolling down at the waist during gym or dance.
Cargo & Wide-Leg Jeans
Woven rigid or slight comfort-stretch denim. Proportioned with room through the thigh and leg opening, featuring the signature internal adjustable button tab waist.
Tiered Dresses & Rompers
Designed with elasticized smocked bodices or tiered skirts that flex across different chest circumferences. The key determinant is torso rise so rompers don't ride up.
Tankinis & One-Piece Swim
Double-lined chlorine-resistant fabrics with full rear coverage. Swimwear naturally relaxes and expands slightly when submerged in water.
Justice Sizing & Fit Questions
Common answers from parents navigating girls' and tweens' sizing transitions.
Justice fits true to standard American youth sizing. Tops and hoodies have a modern relaxed fit that isn't constricting, while jeans and woven shorts feature inner adjustable button elastic tabs so you can tailor the waistband fit by up to 2 inches.
Slim sizes (6S–16S) take approximately 2 inches off the waist and hip measurements while keeping the standard full inseam length so pants don't slip down. Plus sizes (10P–24P) add 2 to 3 inches of room through the chest, waist, and hips while maintaining proportional torso and leg lengths so pants don't drag on the floor.
For graphic tees and fleece hoodies, sizing up gives a comfortable, trendy oversized look that lasts longer through tween growth spurts. For leggings and swimwear, sticking with the smaller size provides the best snug, non-slip fit since the fabrics have high elastane stretch.
Justice cotton graphic tees may experience slight natural shrinkage (approx. 2–3%) if washed in hot water or dried on high heat. To prevent shrinkage and preserve graphic glitter, foil, or screenprints, wash in cold water with like colors and tumble dry on low or line dry.
Inside the waistband on both the left and right hip, there is an elastic strap with buttonholes and an interior flat button. You simply pull the elastic tab tighter and secure it over the button to cinch the waistband by up to 2 inches without bunching.
Youth Big Kids sizes convert to Women's sizes by adding approximately 1.5 to 2 sizes. For example, a Justice size 4 Big Kids sneaker fits a standard adult Women's size 5.5–6, and a Justice size 6 Big Kids fits a Women's size 7.5–8.
