Child size coats, sleeveless gilets or vests and a coordinating hat.  Suitable in lots of fabrics from Demin and corduroy to fleece fabrics.  I especially like view A which is made in a cotton type fabric and paired with a contrasting corduroy collar - may be suitable for a "waxed jacket" look.  The sleeveless vests are ideal for children to throw on to add another layer, especially when made in a novelty fleece fabric
