What Size Lululemon Am I? The Expert’s Definitive Guide

Finding your perfect Lululemon size can feel like cracking a secret code. It’s not as straightforward as traditional sizing charts, and vanity sizing? Forget about it. Lululemon prioritizes fit and performance, which means understanding your body measurements and how they translate to Lululemon’s unique sizing system is crucial. Generally, most people find their Lululemon size to be one to two sizes larger than their typical clothing size. Let’s dive deep into navigating this stylish and functional apparel landscape.

Decoding the Lululemon Sizing Puzzle

Lululemon uses a numerical sizing system ranging from 0 to 20, and sometimes beyond for specific items. This numerical system corresponds to measurements in inches. While there’s no direct conversion to small, medium, or large, we can broadly categorize it:

Sizes 0-4: Generally align with XS
Sizes 6-8: Typically correspond to S
Sizes 10-12: Often equate to M
Sizes 14-16: Usually align with L
Sizes 18-20+: Generally equate to XL and beyond

However, this is a very general guide. Your actual size depends on several factors:

Your Body Shape: Are you pear-shaped, apple-shaped, hourglass, or something else? Lululemon designs for different body types, but understanding yours helps you choose the right styles and sizes.
The Specific Item: A bra size will differ significantly from a leggings size. Even within leggings, different styles (like Aligns vs. Wunder Trains) have different fits and sizing considerations.
Your Preferred Fit: Do you like your leggings super compressive or more relaxed? Do you prefer your tops fitted or flowy?

The best approach is always to take accurate body measurements and compare them to Lululemon’s size charts for the specific item you’re interested in. You can find these charts on their website for each product. Let’s break down the key measurements:

Bust: Measure around the fullest part of your bust, keeping the tape level.
Waist: Measure around your natural waistline, which is the narrowest point of your torso.
Hips: Measure around the fullest part of your hips, keeping the tape level.
Inseam: Measure from your crotch down to where you want the hem to fall (usually the ankle bone). This is especially important for leggings and pants.

Finding Your Fit in Leggings: A Case Study

Leggings are arguably Lululemon’s most iconic product. Let’s examine how sizing can vary across popular styles:

Align Leggings: Known for their buttery-soft Nulu fabric and minimal compression, Aligns tend to run true to size or even slightly large for some. If you’re between sizes, consider sizing down for a snug fit.
Wunder Under Leggings: These come in different fabrics (Luon, Luxtreme) and rises. Luon tends to be more compressive than Nulu, while Luxtreme provides a sleek, supportive feel. Refer to the specific fabric guide for sizing recommendations.
Wunder Train Leggings: Designed for high-intensity workouts, Wunder Trains offer maximum support and compression. Many people find they need to size up in Wunder Trains, especially if they prefer a less constricting feel.
Fast and Free Leggings: Engineered for running, these leggings have a lightweight, barely-there feel. They generally run true to size, but the compressive fit might feel snug at first.

Pro Tip: Read product reviews! Lululemon customers often share valuable insights about sizing and fit in the reviews section. Pay attention to comments from people with similar body types to yours.

The Importance of Trying On (If Possible)

While online shopping is convenient, nothing beats trying on Lululemon items in person. If you have a local Lululemon store, take advantage of their knowledgeable staff who can help you find the perfect fit. They understand the nuances of each style and can offer personalized recommendations. Don’t be afraid to try on multiple sizes and move around in the clothes to ensure they’re comfortable and functional for your activities.

Understanding Fabric Differences

Lululemon uses a variety of proprietary fabrics, each with unique properties and sizing considerations. Here are a few key fabrics to be aware of:

Nulu: Buttery-soft, lightweight, and ideal for yoga and low-impact activities. Less compressive.
Luon: Supportive, compressive, and moisture-wicking. Suitable for a wider range of activities.
Everlux: Highly breathable, quick-drying, and engineered for high-intensity workouts.
Luxtreme: Sleek, supportive, and cool to the touch. Offers moderate compression.
Swift: Lightweight, durable, and water-resistant. Often used in outerwear and running apparel.

Knowing the fabric composition can help you predict how an item will fit and perform. More compressive fabrics often require sizing up, while more relaxed fabrics might allow you to size down.

Frequently Asked Questions (FAQs) about Lululemon Sizing

I’m between sizes. Should I size up or down?

What if I’m losing weight? How often should I remeasure myself?
- If you’re actively losing weight, it’s a good idea to remeasure yourself every few weeks to ensure you’re buying clothes that fit properly.

How can I tell if leggings are too big?
