How to growth proof my son's clothes

[fashionfirst]

Hey, I'm new to sewing and making shirts and pants for my 3YO
Since he's growing so fast (mostly taller!), I want tips and tricks to make the clothes last longer. I know about using a big hem on pants, but what about shirts and other common kid clothes?

Any advice on making clothes that can adjust as he grows?

use some elastics with buttons as a waist adjuster for kids' pants. they're really effective.

Totally get it! 3‑year‑olds grow like they’re training for a height competition. For shirts, adding a deeper hem or using cuffed sleeves you can unfold later works great. Raglan and drop‑shoulder styles also buy you extra months because it works even if the size changes
