What to Wear in August in Chicago: Late-Summer Outfits & Transitional Style Tips
August in Chicago can be one of the trickiest times of year to get dressed. The days can still be hot and humid, but there is often a noticeable shift in the air as summer starts winding down. Suddenly, your favorite summer dresses feel a little too summery, while it is still far too warm to fully embrace fall fashion.
The good news? You do not need to completely change your wardrobe overnight.
As a Chicago personal stylist, I love using August as a transition month. The key is to keep your favorite summer pieces in rotation while gradually introducing richer colors, lightweight layers, and a few early-fall staples.
Here are some of my favorite ways to get dressed in Chicago in August while looking polished, current, and seasonally appropriate.
1. Keep Wearing Your Summer Basics
There is no reason to put away your white jeans, tank tops, lightweight trousers, or summer dresses just because the calendar says August.
Instead, think about how you can style them in a way that feels slightly more polished and transitional.
For example, try:
White jeans with a fitted tank and lightweight blazer
Wide-leg trousers with a simple sleeveless top
A midi dress with a structured handbag and flats
Denim shorts with a button-down shirt
A simple tank with tailored pants and statement accessories
One of my favorite styling tricks is to keep the outfit simple and let your accessories make it feel intentional.
A great pair of shoes, structured bag, sunglasses, belt, or jewelry can completely change the look of a basic summer outfit.
2. Start Incorporating Lightweight Layers
One of the easiest ways to transition your wardrobe from summer to fall is through layering.
Chicago weather can change throughout the day, so lightweight layers are not only stylish, they are practical.
A few pieces worth having on hand in August include:
Lightweight blazers
Linen or cotton button-downs
Cardigans
Lightweight denim jackets
Fine-gauge sweaters
Lightweight trench coats
A blazer is especially versatile because it can make a simple summer outfit feel instantly more polished.
For a workday, try a tank or sleeveless blouse with tailored pants and a lightweight blazer. For a more casual look, pair a blazer with jeans, a simple tee, and flats or sneakers.
3. Introduce Fall Colors Without Going Full Fall
You do not have to start wearing burgundy sweaters and suede boots in August.
Instead, introduce fall colors in small doses.
Think:
Chocolate brown
Burgundy
Olive
Camel
Navy
Deep red
Rich gray
Try adding these colors through accessories first. A brown leather bag, burgundy ballet flats, or olive trousers can make an otherwise summery outfit feel more transitional.
This is one of my favorite ways to make a wardrobe feel current without buying an entirely new set of clothes every season.
4. Use Your Shoes to Transition Your Outfits
Shoes can make a surprisingly big difference in how seasonal an outfit feels.
In early August, sandals and lightweight sneakers still make perfect sense. As the month progresses, you can start incorporating more transitional footwear.
Try pairing summer pieces with:
Ballet flats
Loafers
Silver or metallic flats
Fashion sneakers
Mary Janes
Lightweight ankle boots later in the season
You can even wear a summer dress with loafers or ballet flats instead of sandals to make it feel a little more polished and appropriate for the transition into fall.
5. What to Wear to Work in Chicago in August
Getting dressed for work in August can be especially challenging. You want to stay cool outside, but offices can be freezing thanks to aggressive air conditioning.
This is where layers become essential.
Some easy summer work outfit combinations include:
Option 1: Tailored trousers + sleeveless blouse + lightweight blazer + flats
Option 2: Midi dress + blazer + loafers
Option 3: White jeans + polished knit top + blazer + pointed flats
Option 4: Wide-leg pants + fitted tank + lightweight cardigan + structured bag
The goal is to create an outfit that works for both the heat outside and the air conditioning inside.
6. Start Thinking About Your Fall Wardrobe Now
August is actually one of the best times to start thinking about your fall wardrobe.
Rather than waiting until September and realizing you have nothing to wear, take a look at what you already own.
Ask yourself:
What did I actually wear last fall?
What pieces still fit my lifestyle?
Are there gaps in my wardrobe?
What pieces need tailoring or alterations?
What do I need for work?
What do I need for weekends and social events?
Are there items I keep buying but never wearing?
This is also a great time to do a wardrobe edit.
Before buying new fall clothing, make sure you know what you already have. A closet full of clothes does not necessarily mean you have a functional wardrobe.
The goal is to create outfits, not simply accumulate pieces.
7. Do Not Rush Into Fall Shopping
One of the biggest mistakes I see when transitioning between seasons is shopping too early and buying pieces simply because they are labeled "fall."
You do not necessarily need a new sweater, boots, or jacket just because retailers have started releasing fall collections.
Instead, shop strategically.
Start with the pieces that will give you the most outfit combinations. For example, a great pair of jeans, versatile trousers, a polished blazer, or an everyday shoe may have a much bigger impact on your wardrobe than a statement piece you will only wear occasionally.
If you are considering a larger fall wardrobe refresh, August is a great time to evaluate what you actually need before you start shopping.
8. Think About Your September Calendar
Another reason I recommend planning your fall wardrobe in August is that September tends to fill up quickly.
Between returning to the office, networking events, dinners, weddings, travel, and social plans, you may suddenly find yourself needing several outfits at once.
Look at your upcoming calendar now.
If you have a wedding, work event, date night, conference, or special occasion coming up, start planning those outfits before you need them.
A little preparation can save you from the classic "I have nothing to wear" moment.
The Best August Outfits Are Transitional, Not Completely Fall
When getting dressed in August in Chicago, you do not have to choose between summer and fall.
Instead, combine the two.
Wear your favorite summer pieces, then introduce transitional elements through layers, shoes, accessories, and color. This creates outfits that feel seasonally appropriate without looking like you are rushing through the seasons.
And most importantly, you do not need an entirely new wardrobe every time the weather changes.
Sometimes, you just need a fresh perspective on the pieces you already own.
