Casual summer office outfits for jobs and internships

Whether you’re starting an internship or a new job after graduation, the buildup and the first few weeks of onboarding can be a mix of nerves and excitement. You’re meeting new people, being introduced to new topics, understanding different ideas, and getting acclimated to a new corporate environment. The stimuli are endless.

But after the excitement of the first few weeks wears off, all we’re really left with is the excitement of dressing up. Just kidding. Jobs can be an extremely rewarding part of our lives or something.

Dressing up for your job can really get you in the mood to go to work and be extremely productive. It’s the reason I wear jeans on my work days because there is something uncomfortable about jeans that makes me productive. Luckily, internships and jobs are starting to be in person, which means people will actually see what you wear.

While putting together outfits for work during every other season requires layering, over the summer, we need breathable clothing.

For many decades now, women have been subject to intense public scrutiny for what they wear to work — from whether the pantsuit is too masculine, or a dress isn’t “business-y” enough, or a skirt is too provocative, we have heard all kinds of comments.

The bottom line of this scrutiny is not about what we should or shouldn’t wear to work. It was always about us being at work in the first place. (More on how “professionalism” is just code for oppression here.)

But newsflash, women are in the workforce, and we are crushing it, obviously.

However, we are still subject to dealing with the tricky issue of dressing for work in the summer. If you are comfortable wearing a pantsuit in 90F weather, by all means, be my guest. But for those of us who aren’t, here are a few things to keep in mind when getting dressed for work in the summer:

Tips for Dressing for Work & Internships in the Summer:

  • Favor breathability: Think breathable fabrics – satin, silk, linen, cotton – and silhouettes – flowy, draped, loose.
  • Warm neutrals with bright colors: The workplace is generally not a place to wear your favorite neon dress, but that doesn’t mean you can’t incorporate some color. Mix warm neutrals like beige and chocolate with a pop of blue or yellow accessories – heels, belt, bag.
  • Conference room blazer: While when you don’t need to be wearing a blazer when you’re just sitting at your desk, it’s good to always take one with you and have it on hand in case of a conference room meeting. Those meetings tend to be more formal, and you’ll likely be expected to wear a blazer — also, they usually have A/C, so don’t worry.
  • Balance when it comes to showing skin: While I believe you should wear what makes you feel comfortable, unfortunately, there’s an undeniable power dynamic at play. You’re a young professional who would most likely like to get hired full-time or receive a good recommendation, so it’s better to stay on everyone’s good side and play it safe.

Now, here are some casual summer office outfit formulas to get you started with your outfit planning for your summer job.

4 Casual Summer Office Outfit Ideas That You Should Try

1. Pencil skirt + silky blouse + blazer

If Elle Woods taught us anything, and let’s be honest, she taught us a lot, it’s that pink is a powerful color. Wear different tones of pink for a mix of strength and warmth.

A pencil skirt is a workplace staple, but a satin fabric keeps it cool during the summer. Pair it with a silky top that is both professional and stylish, like this hot pink one.

2. Jeans + white t-shirt + tweed blazer + heels

Jeans and a white T-shirt to work? You heard me. The power of heels and tweed will prove me right.

Pair a nice white T-shirt with some nice jeans with no rips, and then accessorize with some elegant pieces. Pointed-toe heels are classic office wear. A blue shade will complement the jeans while also showing a pop of summer. Lastly, while tweed blazers can look a bit outdated when paired with casual clothing, the outfit will balance itself out.

Don’t be scared of mixing colors, and blue and orange are complementary colors.

3. Polo shirt + skirt + booties

A little inspired by Rachel Green and in part inspired by my obsession with equestrian style, this is my favorite work outfit. Polo shirts are formal and yet casual depending on how you accessorize. So again, use the power of tweed to your advantage and pair a small polo with a white tweed skirt.

Finish off your look with some booties and a matching blazer, like this one, that complements the color but adds an on-trend animal print detail that isn’t too extravagant.

4. Midi skirt+ white button-down shirt + matching accessories

I’ve never liked how midi skirts looked on me, and I thought it was because of my height. But I’ve realized I just never really had the occasion to wear one and dress it up.

Midi skirts have a mature vibe to them, but in your early years, choose one with a fun print like this animal print and pair it with a classic white button-down.

Finish off your look with some bold accessories — nothing looks more fierce than red and animal print, and yet the combo looks tasteful.

If you were feeling nervous about your first day, I hope this makes you at least a little excited about what you wear and a little calmer knowing you have some ideas. Remember that you should wear what makes you feel comfortable and able to deliver your best work.

Outfits Under $100: An Affordable Style Guide for Summer Internships

Outfit #1 – Business Formal

Business Formal


Dressing business formally doesn’t have to be as hard and boring as it looks. 

Versatile pieces are key to rocking this dress code. Don’t waste time agonizing over creating the perfect outfit every morning. You can look stylish and polished every day by mixing and matching the basics. (See where to shop for work clothes on a budget for places to get these basics.)

Black cigarette pants are a staple in my closet because they make for the most versatile bottoms, and they’re slimming, chic, and professional. Paired with blouses or button-ups, the mix-and-match possibilities are endless. 

Tip: I like to tuck the front of my blouse into my bottoms, right where the button is, and have the rest flow out. It adds a personal touch and a little detail to the outfit.

Outfit #2 – Business Casual

When dressing business casual, you don’t want to cross the thin line of looking too casual, but you still want to appear more relaxed than you would when dressing business formal. 

A simple fitted tee and trousers make for a simple, comfortable outfit, but it can be too casual. When in doubt, put a blazer over it. I like to opt for a colored boyfriend-styled blazer to brighten up my look. Finish with heels.

Outfit #3 – Casual Fridays 

Casual Fridays 


Some offices participate in casual Fridays, where the dress code is more relaxed at the end of the week. This is where you get to show off your personality. 

For this look, trade in your blazer for a cozy cardigan sweater and ditch those heels for a comfortable pair of loafers. Layered necklaces and bracelets, a sleek wristwatch, fun earrings, or a neck scarf will add detail and personal flare to any outfit. Just make sure to keep it simple.

Note: Not all offices do casual Fridays, so make sure you check in with your supervisor!
