A very thin serif face with softly bracketed, slab-like serifs and gently rounded stroke endings. The letterforms keep a clean, upright construction with open counters and a calm, even rhythm, while the hairline weight gives it an airy texture. Curves are smooth and slightly generous (notably in O/Q and the numerals), and the overall spacing feels measured, producing an elegant, lightly drawn page color.
Best suited to display typography such as magazine headlines, pull quotes, fashion and beauty branding, and elegant invitations or menus. It can work for short editorial passages when set large enough with comfortable leading, where its fine strokes and rounded slab serifs can remain clear.
The font conveys a quiet, cultivated tone—poised and literary rather than loud. Its hairline build and softened details suggest a refined, boutique sensibility, suited to settings where subtlety and restraint are part of the voice.
The design appears intended to blend a classic serif structure with softened, rounded slab-like detailing, producing a modern refined look with a gentle, crafted feel. The emphasis is on elegance and clarity through open forms and controlled, consistent rhythm rather than heavy contrast or dramatic gesture.
Distinctive details include a graceful Q tail, a lightly curved leg on R, and numerals that feel classic and readable at display sizes. The thin strokes and small serifs create a crisp, minimal presence but will ask for sufficient size and contrast in use.
