I'll start off...
Leggings/trousers for my baby were perfect sizes but for the waists. Bands were cutting into tummy. So I stretched waist bands with hangers overnight. Perfect. Still breaking past the age brackets. Be careful though, some materials would overstretch. I'd rather this though than the cutting in... or... you can save for later.
Body suits - I did chop off legs of a few for emergency home wears. Just an interim till I get new ones. Can also make trendy / weather practical by throwing top/dress on top.
