Butter Cotton Fleece-Lined Sweatsuit
WHY KONNY?
The perfect outfit for daycare or school.

“It's the perfect outfit for school!”
“My kid asks to wear this set almost every day!”
Our Butter Cotton Sweatsuit Set garnered rave reviews and sold out as soon as we released it.
Now it's back as a warm winter version.

After I saw how red my son's face was in pictures his school had taken of him,
I learned it isn't always the best idea to dress him in the thickest clothing just because it's winter.
After all, kids run around and play indoors in the wintertime, too!
Our Butter Cotton Fleece-Lined Sweatsuit has just a thin layer of fleece on the inside,
keeping your little one cozy without causing them to overheat.

This sweatsuit was made with the same Konny Butter Cotton you know and love, but it's now even sturdier.
We all layer an undershirt on cold days--
the high-quality cotton doesn't lose its shape
even if you layer underneath.

Just grab a set on winter mornings, and you're good to go!
Without having to worry about putting together your child's outfit each day, you'll find you have so much more time on those busy weekday mornings.

So soft and makes mama’s life easy

Loveee having a sweatsuit set that I can just pull out and not worry about matching baby’s top with bottom! Fabric is soft and comfy for babies with sensitive skin.

We completely agree that the fabric is very soft! There’s nothing like a sweatsuit set to help you get ready quickly during a busy morning routine! Thank you for choosing Konny :)

So soft and cozy

My toddler loves wearing this set! I bought it in two colors for the fall/winter and they're perfect. Soft, warm and looks nice. I wish there were smaller sizes for my younger baby.

Thank you for taking the time to leave a review. We're so happy to hear that your little one loves it. There are sizes available for 1-2 years as well, so feel free to check them out!

High quality fabric

Very soft, doesn’t peel when you wash

Thank you so much for your review! We take pride in using high-quality fabrics that are gentle on little ones 😊

M
Miranda S. (Taipei, TW)
got pretty much all the colors!

They are so soft and buttery that I ended up getting cream, pink, and blue! All nice to style and wear! I wish they released bigger sizes for the 2-3-year-olds with the diaper design for taller babies! Can't wait for more colors and patterns!

We're so happy to hear you love the softness and variety of colors. We appreciate your feedback about bigger sizes for toddlers, and we’ll definitely keep it in mind for future collections. Stay tuned for more colors and patterns!
