We use UK size for our clothes but as every child is individual, it is always better to check their height and waist size before purchasing.

The clothes should last your boy at least two years and the beauty of Smart Alek style is that different lengths of shorts and trousers give different looks. All our trousers have 3 cm allowance in the hem that can be let out to last longer, though, like Tom Sawyer, we prefer our trousers shorter.

Our advice, when in doubt, go a size bigger!
