Frequently Asked Questions About Kids Activewear

What sizes are available in your kids activewear collection?
Our kids activewear includes a mix of baby, toddler, and youth sizing depending on the style. Size availability varies by item, so the best way to confirm is to open the product and review the size options shown on that page.
Does Cecil & Lou activewear run true to size?
Most styles fit true to size. If your child is between sizes, we usually recommend sizing up for a more comfortable fit, especially for fitted shorts, athletic sets, and slimmer athletic dress styles.
What is included in the kids activewear collection?
This collection focuses on girls activewear and kids athletic wear, including athletic dresses, tennis-inspired dresses, sporty sets, skirts, and easy tops made for play, practice, and everyday wear.
What is the difference between a knit tennis dress and a lycra tennis dress?
A knit tennis dress typically has a soft, classic feel and looks great dressed up or down. A lycra tennis dress is usually stretchier and more performance-forward, with a smoother feel that is great for movement. The product description will call out the fabric and details for each style.
Do your girls athletic dresses have built-in shorts or bloomers?
Some athletic dress styles include matching bloomers or a short layer, and others are dress-only. Check the product photos and description for what is included so you can plan the best fit and coverage for active days.
What should my child wear under an athletic dress?
For playground and school days, many parents choose bike shorts or bloomers for comfort and coverage. If the dress includes matching bloomers, that is usually the easiest option. If it does not, a simple pair of shorts works great.
Is this activewear only for sports like tennis and golf?
Not at all. While many pieces are tennis and golf inspired, they are made to be worn beyond the court, like school, travel, weekend outings, and play. Think kids sportswear that still looks like classic boutique style.
What fabrics are used in your kids athletic wear?
Fabrics vary by style, but you will see options like soft knits and stretchy performance materials designed for comfort and movement. Each product page lists the fabric details so you can choose what works best for your child.
How do I wash and care for kids activewear?
For most items, machine wash cold on a gentle cycle and tumble dry low. Avoid high heat to help preserve stretch, shape, and color. If an item has special trim or detailing, follow the care notes on the product page.
Are these pieces lightweight for warm weather?
Yes, many of our kids activewear styles are designed for warm-weather comfort, including sleeveless athletic dresses and breathable sets. If you need the lightest option, look for stretch-performance fabrics and sleeveless cuts.
Do you have matching sets or coordinated activewear outfits?
Yes, you will find coordinated kids athletic outfits like top-and-short sets and matching sporty looks. If you are trying to build a full outfit, check the collection for coordinating pieces in the same color or stripe theme.
What if the size does not fit?
If something is not the right fit, you can use our return or exchange process based on the item condition and policy guidelines. You can review details here: Return Policy.
