Soft and gentle on delicate skin,
keeping your little one cozy all day.
Finished with a festive
holiday checkered print.
Daily loungewear sets usually
get worn down pretty fast
after a few washes.
We really set out to make
something super soft and cozy
that holds up wash after wash
without any pilling.
Let's look into materials that
stay super soft without losing
their shape or quality!
We should offer a lot of
different patterns to make daily
styling fun and easy.
My go-to loungewear every season.
Amazingly soft, stretchable, and comes
in the prettiest colors and designs!
Honestly, Konny is so reliable it
hardly needs a review.
It’s perfect to wear on its own, and
functions as an amazing inner layer
on cold days!
So soft, and the ankles stay right in
place! Konny loungewear never
disappoints. Definitely grabbing
another set.

Care Instructions
In order to ensure you receive the highest quality product possible, we package all our orders with a Micro-Pak® PE sheet, a functional antibacterial and moisture-proof packing material that has passed U.S. and European safety standards.
for Fool-Proof Selection
First, every brand uses different
sizing system. Some go by age,
others by height, and sometimes
the standards aren’t very clear.
With standards all over the place,
it’s only natural you’d feel a bit lost.
BRAND A
SIZE 3, 5, 7, 9...
BRAND B
1-2Y, 3-4Y, 5-6Y...
BRAND C
80, 90, 100, 110...
Meanwhile, kids grow at their own pace
and have different body types,
even at the same age.
While it’s more accurate to use height
and weight over age, some kids are
naturally slimmer or chubbier.
“My baby wears a size 80
in another brand. Should I buy
the 1-2Y(80) size at Konny too?”
We heard this question a lot.
So we simplified our sizing into
one clear standard.
This system is more commonly
used by global brands,
making size selection easier.
| OLD | NEW |
|---|---|
| Age | Height (cm) |
| 3M, 6M, 18M, 24M 1-2Y, 2-3Y, 3-4Y, 5-6Y |
60, 70, 80, 90, 100, 110, 120, 130 |
* We’ve added a new 130 size.
What Do Our Sizes Mean?
Optimal for children 70~80 cm tall.
A size 80 item on an 80 cm child
will most clearly show the product’s
intended fit (slim fit, regular fit, overfit).
On a 70~75 cm child, it will
be roomier but still fit well.
STEP 1
Check the standard size guide
on every product page and select the
best size based on your child’s height.
1 Top of Product Page
2 Bottom of Product Page
STEP 2
Consider your child’s weight and
body type. If your child is on the
slimmer side, it maybe a good idea
to purchase one size down.
Refer to the models below for guidance.

SETS
My kid wears a size 90 in other brands. Does that mean I should buy a size 90 at Konny too?
Every brand has different sizing standards, even if the sizes appear identical in number. At Konny, a size 90 means it is optimal for a child who is 90 cm tall. However, another brand’s size 90 may have been made for an 85 cm child. We recommend that you refer to our standard size guide, the actual measurements for each product, and the model shots to make the most informed decision.
My child usually wears a size 100, but I’d like to know if Konny’s clothes tend to be more relaxed fit or slim fit.
We believe children’s clothes should be comfortable first and foremost, so we tend to make our items more relaxed fit. However, the fit can vary depending on the category or item. Our leggings are slim fit, while our t-shirts come in both regular fit and overfit. Unless your child is especially skinny or chubby, a Konny size 100 will fit a child 90-100 cm tall very well.
Is last year’s size 100 the same as this year’s size 100?
All our sizes are now a bit roomier. Our new size 100 has been designed to fit a 100 cm child perfectly, so you may notice that items are a bit longer or roomier than last year’s 3-4Y (100) size.
My child has grown out of the Newborn 24M size, so I’d like to move onto the Baby sizes. What do you recommend as a next step?
As we switched from an age-based system to a height-based system, we got rid of the Baby sizes category as well. According to our old sizing system, the 24M size was optimal for 80-85 cm children. Now, if your child is taller than 85 cm, we recommend size 90 or higher. Please refer to our standard size guide and the product’s actual measurements before purchase.
