Toddler PJs that aren’t sausage casings???

We have an almost 15 months old. I actually don’t know her exact current weight and height but she’s always been near the top of charts, but proportional. She’s current in a mix is 12M to 2T size clothes. My issue is with the toddler pajamas. Why are they all so tight in the limbs??? ( I know legally why, but like WHYYY).

Can anyone recommend PJs that aren’t so tight?

I struggle especially in the arms. As a reference we have the Kyte baby pajamas in 18M and 2T and the tops are way to tight in the arms and really annoying to put on. I’ve tried sizing up in a couple of brands but they just get longer not looser. Her normal day clothes fit fine.
