Veils are made from either a circle (up to and including 108″) or an oval (over 108″).
The size includes the ‘train’ (the longest part) and the ‘blusher’ (the shortest part, sometimes worn over the face). These two lengths are added together to give the total veil size. E.g. 45″ train and 27″ blusher = 72″ veil.
