Choosing the right size is one of the most important steps when shopping for activewear in the US. A proper fit can improve comfort, mobility, and confidence—whether you’re training, stretching, or wearing activewear as part of your everyday routine.
While style and color often catch attention first, fit is usually what determines long-term comfort and satisfaction.



Understanding Activewear Fit and Sizing in the US
Activewear sizing can vary across brands in the US, especially when it comes to fabric stretch, compression level, and intended use. Some designs focus on performance and support, while others prioritize comfort and casual wear.
When browsing well-known activewear brands such as Lululemon, shoppers may notice that sizing can differ by collection or activity type.
Here are a few general guidelines:
Sports bras: Choose based on activity level, not just size, to ensure proper support.
Tops: A good fit should allow free movement without feeling restrictive.
Leggings: Waistband comfort and stretch are essential—try bending or stretching to check flexibility.
Why Fit Matters When Shopping for Activewear
The right fit can help prevent discomfort, reduce distractions during movement, and improve overall confidence. Clothing that fits well often leads to better performance and fewer returns.
If you’re planning to update your activewear wardrobe or try a new style, understanding sizing beforehand can make the shopping experience smoother and more enjoyable.
