The modern workplace demands versatile dressing—outfits that can move from casual meetings to formal presentations without skipping a beat. From relaxed dresses with trainers to structured blazers over shirt dresses, today’s office wardrobes are about polished comfort, not rigid dress codes.

Here’s your detailed guide to mastering casual to smart office dress combos, including styling ideas, the best UK & USA brands, and how to use Tellar.co.uk to find your perfect fit in every store.

👗 Key Casual-to-Smart Dress Combos That Work

1. Knit Dress + Tailored Blazer

A fitted or ribbed knit dress offers softness and stretch for casual comfort.
Add a single-breasted blazer in wool, crepe, or cotton to structure the look.
Switch between loafers and low block heels depending on the setting.

Great for: hybrid workers, creative roles, client-facing days.

2. Shirt Dress + Belt + Longline Coat

Shirt dresses transition perfectly between casual and smart depending on accessories.
Add a belt to define the waist and a structured coat to finish the look.
Dress down with white trainers or up with heeled ankle boots.

Tip: Go for a midi-length to keep it office-appropriate and flattering across heights.

3. Wrap Dress + Loafers or Heels

A jersey or crepe wrap dress is both forgiving and flattering.
Easily layered with a cropped cardigan or blazer.
Works across all seasons with simple footwear swaps.

Great for: hourglass, rectangle, and apple body shapes due to waist emphasis.

4. Polo Knit + A-Line Skirt

Swap stiff blouses for soft knits or a ribbed polo top.
Pair with a midi A-line skirt in pleated or structured fabric for balance.
Add tights and loafers or pointed flats for polish.

Great for: business-casual workplaces that encourage subtle flair.

5. Tunic Dress + Trousers or Leggings

For relaxed offices, layering a tunic or oversized shirt dress over cigarette pants or tailored leggings is ideal.
Add ballet flats or structured mules.

Tip: Use accessories (a leather belt, sharp bag, sleek earrings) to elevate the silhouette.
