Office Siren Blazer Collection: Power Style.

Office Siren blazers are the core of the trend — structured shoulders, narrow waist, a cut that takes up space.

Why the blazer is the center.

Office Siren works through silhouette, not color. And no piece defines a silhouette as clearly as a blazer. Overcut shoulders, tapered middle, length to the hip — that's enough to set an outfit. Everything else falls in line. In our Office Siren Collection you'll find the matching trousers and skirts.

How you wear the blazer.

Open over a simple top is the classic. Closed as the only layer works in the evening. Oversized feels more relaxed, tailored feels sharper — both are Office Siren, both belong in the office. For those who want to take the look darker, find Dark Office Siren blazers with gothic influences.

What's in the collection.

Blazers in black, anthracite and deep tones. Single-breasted, double-breasted, with and without collar. Materials from structured wool to flowing fabric. Every piece is cut for the Office Siren Look — power dressing without costume.
