Size Guide

Pettilia - Size & Fit Guide
A Note From Us 💕

We know that finding Lolita pieces in larger sizes can be frustrating. That’s why we worked closely with our brand partners to develop sizes 1X–3X that truly fit.

Every size was tested on real plus-size models, refined through multiple sample rounds, and continues to improve with your feedback.

You are not "between sizes" — we just haven’t made your size yet. And we’re working on it.

📍 Measurement guide — point by point
1. Bust
Measure around the fullest part of your bust, keeping the tape level and snug but not tight. Wear a well-fitting bra.
2. Waist
Measure around your natural waistline — the narrowest part of your torso, above your belly button. Breathe normally.
3. Hip
Measure around the fullest part of your hips, keeping the tape level and snug.
4. Shoulder Width
Measure from the edge of one shoulder bone across your back to the edge of the other shoulder bone.
5. Dress Length
Measure from the highest point of your shoulder down to where you want the hem to fall.
6. Upper Arm
Measure around the fullest part of your upper arm, with your arm relaxed at your side.
7. Sleeve Length
Measure from your shoulder bone down to your wrist bone, with arm slightly bent. (For long sleeve dresses or blouses.)
✨ UNDERSTANDING OUR FIT SYSTEM
🌸 What is Shirring & Why It Matters
Shirring (elastic gathering) is the secret to comfortable plus-size Lolita dressing. It is sewn into the back panel of our JSK and OP dresses, providing 10-15cm of comfortable stretch.
Combined with back lacing, shirring creates a flexible fit system that adapts to YOUR body. No more "between sizes" frustration — the garment stretches to fit your curves while maintaining the beautiful Lolita silhouette.

❄️ Frequently Asked Questions
How does Pettilia sizing work?
Pettilia uses a 1X/2X/3X system built for plus-size Lolita — based on real body data from over 600 plus-size Lolita enthusiasts, not scaled-up straight sizes.
What is 'shirring' and how does it help with fit?
Shirring (elastic gathering) is sewn into the back of our JSK and OP dresses. It provides 10–15cm+ of stretch to accommodate different bust sizes, creating a flexible fit system.
I'm between sizes — which should I choose?
For JSK with elastic waists, choose based on bust. For non-elastic waist JSK and blouses, prioritize your largest measurement. When in doubt, size up — Lolita is meant to be dreamy, not tight.
Why doesn't Pettilia use standard S/M/L sizing?
Standard S/M/L is designed for straight-size bodies. Our 1X/2X/3X system is engineered from the ground up for curves — adjusted shoulders, deeper armholes, and strategic shirring.
How do I know if a JSK will fit my bust?
Check the “Fits Bust” range on the product page. Shirring + back lacing provides 10–14cm stretch. If your bust falls within that range, you are good.
Where can I find the size chart for a specific product?
Each product page has a detailed size chart under the “Size & Fit” tab. Use this Size Guide for general measuring instructions and our sizing philosophy.
