Got a pink K1 Gi for my daughter who is just starting BJJ and I didn't want to spend big bucks on a Gi while before knowing this is something she will stick with. First impression of Gi right out of the package is great.
The sizing guide says that a child 51" = K1; my daughter is ~52" and the K1 Gi is about the right size (ever so slightly large). I expect it to be a perfect fit after washing. Color is vibrant and the embroidery of the logo seems to be of good quality. The material of the Gi, while thin and lightweight, appears and feels durable. As an FYI the pants are elastic waist with a drawstring rather than the more traditional Gi pant drawstrings (I don't care one way or another - just mentioning it.) Time will tell how well the Gi stands up to grappling. If my daughter gets 6 to 8 months of good wear and tear out of this Gi while she figures out if BJJ is the sport for her, I will feel that it was money well spent.

Cheep and fit kids great made very good

Got it for my daughter who does BJJ. Styling and has a nice fit to it. Easy to clean and dry as well. No problem with shrinkage at all either. Definitely will be buying more

My son is 7 years old & weights about 75lbs. He usually wears a size 9 or 10
Or large in youth sizes. This fits him great.

These are good quality kids Gis for a great price. The fabric is thick on the coat and a bit lighter/more flexible for the pants. My older child has the blue gi. Both look good and I've never heard any complaints. They love them and I'm happy. The two gis were purchased a year apart, the first one has held up and still looks new. I also, do wash them after 2-3 classes and I've never had any shrinkage or damage from the washer or dryer.
