Women’s Sizing Guide for Canadians
Walking into a fitting room (or clicking “Add to Cart”) shouldn’t feel like a guessing game. In Canada, women’s clothing sizing can vary by brand, category, and even by fit—Missy, Plus, Petite, and Teen/Young Women’s Fit all follow slightly different logic. This guide is here to simplify things so you can shop Online Warehouse Sale with confidence, and keep your wardrobe and your wallet on the same team—Fashion Affordable.
A visual comparison of Missy, Plus, Petite, and Teen/Young Women’s Fit proportions.
How Women’s Sizing Works in Canada
Most Canadian retailers use a mix of:
- Letter sizes – XS, S, M, L, XL, XXL
- Number sizes – 0–18 (and higher in Plus)
- Category-specific fits – Missy, Plus, Petite, Teen/Young Women’s
At Online Warehouse Sale, you’ll see all of these systems depending on the brand. The key is to match your measurements (bust, waist, hips) to the size chart and consider the fit category.

Missy (Women’s Regular) Sizing
Who it’s for: Most adult women with an average height and curvier bust/hip proportions.
- Designed for balanced curves through bust, waist, and hips.
- Letter sizes (S–XL) and number sizes (around 2–18) are common.
- Rise and torso length are cut for average height (roughly 5'4"–5'7").
Plus Sizing
Who it’s for: Curvier figures that need more room through the bust, waist, hips, and arms.
- Sizes often labelled 1X, 2X, 3X or 16W, 18W, 20W and beyond.
- More ease built into the hip, thigh, and seat.
- Armholes, sleeves, and bust area are cut to avoid pulling and gaping.
Petite Sizing
Who it’s for: Women under about 5'4", regardless of size.
- Shorter inseams, sleeve lengths, and torso proportions.
- Available in both straight and plus sizes in many brands.
- Prevents hems from dragging and shoulders from dropping.
Teen / Young Women’s Fit (Juniors-style)
Who it’s for: Teens and young women with straighter, less curvy proportions.
- Smaller bust, narrower shoulders, and straighter hip/waist line.
- Often labelled Teen, Youth Women’s, Young Women’s Fit in Canada; Juniors in the U.S.
- Tends to include more trend-forward silhouettes and shorter rises.
Find Jeans That Actually Fit
Use your size category and measurements to explore jeans that love your shape back.
Shop Women’s JeansLetter Sizes vs Number Sizes
Here’s a rough guideline many Canadian brands follow (always check the size chart for each item):
- XS ≈ 0–2
- S ≈ 4–6
- M ≈ 8–10
- L ≈ 12–14
- XL ≈ 16–18
In Plus sizing, 1X usually starts where XL leaves off, but the shape is different. A 1X isn’t just a “bigger XL”—it’s cut to support curves better.
How to Choose Your Size Category
If you’re straighter through the hips and bust...
You may find Teen/Young Women’s Fit or the smaller end of Missy sizing works well, especially in tops and dresses. Look for fit notes like “Juniors-style” or “Teen Fit” in the description.
If you’re curvy through the hips and bust...
Missy or Plus will likely serve you better. Jeans labelled “curvy fit” or “room through hip and thigh” are often more comfortable and flattering.
If you’re petite in height...
Look for Petite-specific styles when possible, or inseams listed as short/ankle. When shopping regular Missy or Plus, check inseam length and use it with your measurements (see our How to Measure Yourself guide).
Dresses for Every Shape
From casual day dresses to event-ready styles, find your fit with Missy and Plus sizing.

- Read the fit notes – Look for clues like “Juniors fit,” “curvy fit,” “relaxed,” or “slim cut.”
- Check fabric content – Stretchy knits and denim with spandex are more forgiving than rigid fabrics.
- Compare your measurements – Use your bust, waist, and hips to pick the right size category and number.
- Think about how you like clothes to sit – Oversized? Tailored? Cropped? Your preference matters as much as the size chart.
FAQ: Women’s Sizing in Canada
Why am I different sizes in different brands?
This is completely normal. Brands use different fit models and grading rules. Use your measurements as your anchor instead of relying on the size on the tag.
Is Teen/Young Women’s Fit smaller than Women’s?
Yes—Teen Fit is cut with a smaller bust, narrower shoulders, and straighter hips. If you’re curvier, you’ll likely prefer Missy or Plus.
Can I wear Plus if I sometimes fit an XL?
Absolutely. Many people float between XL and 1X depending on the brand and cut. Choose the size that feels comfortable and supports your shape.
What’s the difference between Petite and Plus?
Petite refers to height; Plus refers to fullness/curve. You can be both Petite and Plus at the same time.
