Back to Work: Stylish Office Outfits to Transition from Summer to Fall
September marks not only the return to the office but also the beginning of fall. After a season of holidays, sunshine and light outfits, this is the perfect time for a fresh start with your wardrobe. But what do you wear in this transitional period between summer and fall, when the weather can be unpredictable and your look needs to be both professional and comfortable?
With these style tips for fall office outfits, we’ll show you how to transition seamlessly into the new season. Think business casual looks, comfortable workwear, and timeless wardrobe essentials that always work. Get inspired by these five back to work outfits – minimalist, feminine and perfect for September and October.
Outfit 1: Blazer + Trousers – the Classic Office Outfit
The foundation of every professional wardrobe remains the suit: a matching blazer and tailored trousers. It’s a combination that always looks polished and never goes out of style. This season, JapanTKY introduces several suits designed with both comfort and elegance in mind. With refined fits and high-quality fabrics, you’ll look sharp all day long without compromising on wearability.
Want to add a more modern, sporty twist? Swap the blazer for a coordinating bomber like the Aya jacket. It keeps your look professional but adds a contemporary casual touch. Pair with sneakers for a business casual vibe, or go for heels to make the outfit extra chic.
Outfit 2: Midi Dress or skirt + Boots – Stylish and Effortless
A midi dress is a true lifesaver on busy mornings. With just one piece, you’re instantly ready for work while looking elegant and feminine. Choose neutral tones like deep black, navy or mocca mousse, or embrace seasonal highlights such as blackberry wine or sapphire. It also looks great when styled with a skirt for an unexpected, fashionable twist.
Pair with heeled boots for a chic yet practical fall office outfit. Shorter dresses and skirts also work, as long as you balance the proportions with taller boots. Add a blazer for formal meetings or a trench coat on the go, and you’ve got a versatile look that transitions seamlessly from the office to after-work drinks.
Outfit 3: Layering with a Jacket and Trousers – Perfect for Fall Weather
Fall weather is known for its unpredictability. One day it’s sunny and mild, the next you’re walking into the office in the rain. That’s why layering is key – it’s not only practical, but also elevates your style.
Start with a strong base like a blouse or top paired with tailored trousers. Add a jacket in a statement material or color to give your outfit more personality – think suede, wool blazers or structured gilets.
A favorite this season is the Karlyn gilet, which instantly upgrades a simple blouse. By building your outfit in layers, you can adapt easily to changing temperatures while creating a look that’s visually interesting and modern.
Outfit 4: Knitwear – Comfortable and Business Casual
Alongside blazers and dresses, knitwear is an essential in every fall wardrobe. It provides warmth and comfort but can also look surprisingly chic – especially in minimalist designs and refined materials.
Combine a lightweight knit sweater with tailored trousers and ballet flats for an effortless business casual look. Or wear a soft knit layered over a blouse for added texture. Cardigans also work beautifully: they’re practical, stylish and perfect for in-between weather.
JapanTKY’s knitwear pieces are designed to be both comfortable and sophisticated, crafted from fabrics such as soft alpaca wool and travel jersey. This makes them versatile essentials that blend seamlessly into your capsule wardrobe.
Outfit 5: Checks – a Timeless Fall Print
Checks are the print of the season and pair perfectly with professional workwear. A checked blazer or trousers instantly adds structure and style to your office look. Go for a full set if you want to make a bold statement.
Prefer something more subtle? Choose one printed item – such as a blouse, skirt or top – and combine it with timeless neutrals. This way, you create a modern yet classic fall office outfit that works season after season.
