Sorry if everyone already knows to do this(!) but I've just discovered this top tip and as helped save me one cash!
Dd is now 10 months old and have found that using her 0-3 dresses (the smock kind) as tops (paired with jeans etc) looks great and saves me buying tops in her size, plus she gets more wear out of some of her gorgeous dresses she's now outgrown.
Thought I would share
