Vow is an incredibly stylised font, strutting its stuff on the typography catwalk. Vow does everything to excess, even when cutting down: where it’s curvy, it’s very curvy, but where it’s thin, it’s thin.
Vow’s regular weight has a certain boldness at text size, but its ultra-thin alternative is much better used at larger sizes, managing to take up very little space even when scaled up. Using a mix of the two creates a subtle emphasis, especially when coloured, which helps to create stunning messages in elegant ways.
