Cut true to size. The peplum is fitted at the natural waist — if you're between sizes, size up for a softer flare or size down for a fitted line.
No. The keyhole tie opens to roughly the upper back — a small triangle of skin visible above the tie. Bra-friendly with a strapless or back-cinch bra.
Hand wash cold or delicate cycle in a mesh bag. Lay flat to dry — never tumble. Cool iron from the reverse if needed. Treated with care, it'll hold its shape through years of wear.
30-day try-on at home. Unworn pieces with tags attached can be returned for a full refund. Free return shipping in the US, no restocking fee.
Orders ship within 1–3 business days. US standard arrives in 3–7 business days with tracking. Free over $99. International shipping available — full details on our Shipping page.

Astrid Blouse
Three ways to wear it.
The Astrid Blouse is cut to layer, mix, and live across the seasons of your wardrobe.
What you're actually wearing.
Beyond the photograph — the materials, the make, the work behind the seams.
Worn by women like you
Built by a small team.
Worn by women who notice.
"We started Oslo because we were tired of fashion that lasted one season. Everything we make is cut to be worn — and re-worn — for years."
Oslo The Label was founded on a single principle: real luxury is felt, not announced. We design every silhouette ourselves. We obsess over fabric weight, line, and how a piece moves on the body. We produce in small batches with partners we trust.
What you wear should outlast the season it was made for. That's the standard. That's the only standard.
