How to Style an Oversized Black Blazer: 5 Easy Looks

How to Style an Oversized Black Blazer: 5 Easy Looks

An oversized blazer is the quickest way to make a simple outfit look finished. Here are five ways to wear ours, from an easy daytime look to an all-black evening.

Why an oversized blazer works with almost everything

A tailored blazer with room in the shoulders and body does two jobs at once. It adds structure, so jeans and a basic top suddenly look planned, and it stays relaxed enough to feel like yours rather than like office wear. That balance is why the oversized cut has outlasted so many trends.

Ours are made to order in Bucharest and adjusted to your height and weight, so "oversized" is a decision, not an accident. The Delulu Blazer is made of organic cotton in black, with a small colourful "DELULU" embroidery on the shoulder. The volume sits where you want it and nowhere else.

Five ways to wear it

  1. With a white baby top and relaxed jeans. A slim top under a roomy blazer is the classic contrast. The white baby top is made with organic cotton from Portugal, so it stays soft and light under the structure of the jacket.
  2. Over wide-leg, low-waist jeans. Volume on top asks for a clean line below. The black mini bag jeans are wide-leg with a low waist and come with a black mini charm bag, which gives the whole outfit a playful finish.
  3. Tone on tone. Black blazer, black top, black trousers. With no colour to compete, the embroidery becomes the only detail, and the outfit looks quietly expensive.
  4. Open, with the sleeves pushed up. Leave the blazer open and push the sleeves to your forearms. It looks effortless, and it shows off whatever you are wearing underneath.
  5. Dressed up for the evening. Add boots or heels, a small bag and one piece of jewellery. The blazer does the rest, and it works as a coat substitute on cool autumn nights.

Details that finish the look

With a blazer this relaxed, the small decisions make the outfit feel intentional.

Delulu or Muse?

Both blazers share the same oversized tailored cut and the same black. The difference is the detail: the Delulu has a small colourful embroidery on the shoulder, while the Muse Blazer carries a small red "Muse" script on the chest. Choose the shoulder if you like a subtle surprise, and the chest if you prefer the detail visible from the front.

Getting the fit right

Every piece is made to order, so we adjust it to your height and weight. Tell us the numbers and we take care of the proportions. Made-to-measure length adjustments are final sale, so decide on the length you want before you order.

Delivery and returns

Allow a little time for your piece to be made, then add delivery: 3–5 working days in Romania, 5–7 in the EU and UK (DHL Express), 7–9 to the USA and Canada (UPS Express) and 8–12 to Australia. Unworn pieces with their tags can be returned within 14 days. Returns are free in Romania; from other countries the customer pays the return shipping.

A good blazer is not about following a trend. It is the piece you reach for when you want to look put together without trying too hard, and one that fits you properly makes that feeling easy.
