I searched high and low for onesie/ bodysuits for my son since he was always off the charts in height.  When he was 9-12 months old he needed 24 month + clothing.

These onesies were very poorly made, cost less than others but I totally got what I paid for and wound up returning them.  They are NOT true to size, very thin quality and totally not worth it.

I will always stick with Carter's from here on in.  May pay a few more $$ but you will get generous sizing, no shrikage in the dryer and you will get nice thick quality 100% cotton.
