All tables are very approximate guides. Cut, style and basic sizing schemes vary between manufacturers and outlets. Size guides indicate an approximate match but there is far too much variation to be certain of an exact fit. Size labels and numbers are different in other countries. Items may show size codes intended for other countries even though they are sold in the UK. Some EU countries operate their own sizing systems which will not match those shown here.
