5 Ways to Wear a Blazer Without Looking Too Formal:

1. Blazer + Graphic Tee + Jeans

The classic combo that always works.

Pair a structured blazer with a vintage-inspired graphic tee and your favorite high-waisted jeans. This combo gives “cool girl off-duty” energy and is perfect for casual meetups or coffee runs.

Style Tip: Cuff the sleeves and add sneakers or loafers to keep it laid-back.

2. Blazer + Biker Shorts + Chunky Sneakers

This is the ultimate athleisure-chic look.

Take your workout set from gym to brunch by throwing on a neutral blazer. It balances sporty and polished for a look that says, “I didn’t try too hard” (but you totally did).

4. Blazer + Slip Dress + Loafers

The perfect day-to-night look that’s comfy yet polished.

Layer a blazer over a satin or cotton slip dress for a balanced outfit that’s feminine and put-together—but not overdone. You can throw on a belt bag or crossbody to keep things playful.

Style Tip: Choose a blazer that hits right at your hip for best proportions.

5. Blazer + Hoodie + Leggings

For those days when you want to feel cozy but still pulled together.

Throw a slightly oversized blazer over a hoodie and leggings for a comfy-casual mix. The hoodie adds streetwear vibes, while the blazer keeps things structured.

Style Tip: Go monochrome (like beige-on-beige or black-on-black) to make it feel more intentional.

• Cozy Hoodie—Aritzia
