I have found a page on facebook that does funky kids clothes and they can be personalised. I can't decide what I think about them yet. A couple of examples of the designs they do are here and here.
They also do accessories and things like scratch mitts, bibs, hats, gloves, scarves, pants, vests, sleepsuits, blankets, duvet & pillowcase sets, taggies, comforters, aprons, oven gloves, bags, teddies with tshirts.
