Casual summer outfit ideas

Anson Belt and Buckle logoNote: Huge thanks to Anson Belt & Buckle for sponsoring this article! I've been wearing Anson belts for years. I love how you can mix and match the buckles and straps, and I think their 1.25″ canvas belts are perfect for summer.

I'm going to show you 10 casual summer outfit ideas from my own wardrobe. But before we dive into the outfits, I want you to pay attention to a couple of things:

First, these outfits are pretty simple. Nothing flashy here. Just classic, somewhat muted colors that work for pretty much any type of person.

These outfits work for two reasons: because the clothes fit well, and because the colors work well together.

Second, everything I'm wearing – the shirts, pants, shorts, shoes and accessories – is all interchangeable. This is because it's all part of the same color palette – olive, navy, light blue, brown, khaki and grey.

This great because it makes getting dressed super easy, and it means you change the whole vibe of an outfit just by swapping out your shoes and accessories.

So you'll probably notice that many of these outfits are just slight variations of each other. Without further adieu, let's look at the outfits (in no particular order)…

Blue linen shorts grey t-shirt

Call me basic, but I love this getup. Light grey t-shirt, blue linen shorts, all white kicks, a sporty dive watch and my favorite square-shaped shades.

It's cool, fitted and fresh, and this outfit always always makes me feel fantastic.

If you want to step things up in terms of formality, you could swap the t-shirt out for a short sleeve button up and opt for boat shoes instead of sneakers.

Furthermore, you could replace the shorts with a pair of khaki chinos – cuffed a couple of times to show some ankle, of course.

This getup has a kind of classy, nautical kind of vibe, like “Do you think he owns a boat?” kind of vibe.

(I don't…at least not yet.)

And of course, if it gets cool at night – like if you're at the beach, you can throw on a lightweight jacket like this nylon windbreaker from J. Crew.

One thing I've been doing with my old, worn out button up shirts is cutting off the sleeves and collar to turn them into short sleeve, band collar shirts.

It's a super casual, super cool look that lets your neck and arms breathe a little – perfect for those hot and humid summer days.

Now, if this outfit is a little too “my dad owns a dealership” for you, you can change the whole vibe by switching the belt, watch and shoes.

This subtle variation feels a little more clean and modern. It's by no means a “street style” look, but it does have a slightly more urban vibe with the classic Reeboks and retro Casio watch.

And of course you could take this getup in a more casual direction by swapping the button up shirt for a plain old crew neck t-shirt – as long as it fits properly.

Grey and brown work really well together. In fact, this is one of my favorite color combinations, and I think it's vastly underutilized.

You could play up this combo by swapping the all white sneaks for a pair of leather Birkenstocks (or sandals of your choice).

Here, I've also swapped the black Casio watch for a Seiko SNK805 on a camo nato strap.

I love this outfit. It's fitted and comfortable, and it has a very earthy, natural vibe to it. Am I going hiking later? Could I start a fire with my bare hands?

Quite possibly, my friend. Quite possibly.

Going back to the idea of repurposing your old clothes that you're not wearing anymore – this next outfit is full of DIY details.

Cuffed olive chino shorts

shirt | loafers

I converted this Ash & Anvil button up shirt from long sleeves to short sleeves, and these Combat Gent olive chinos into cuffed chino shorts.

Dark blue and olive is a great color combination that works equally well formalwear and casual getups.

I could have worn boat shoes, but these perforated loafers from Jay Butler help to dress this outfit up a bit.

You could take this same color combo in a younger, more casual direction by opting for a fitted polo shirt and sneakers.

This is a slightly more sporty feel, but it's still pretty classic and easy to pull off.

Moving on, these linen pants are a new look for me. They're cut quite a bit fuller than most of the pants in my closet, which takes some getting used to.

Linen pants from H&M

It's a different silhouette, and I've got to say: it is very comfortable. Between the extra room through the leg and lightweight fabric, I feel like I could wear these these in 100 degree weather without breaking a sweat.

These pants were a bit of an experiment for me. So ,rather than going high end, I got them on the cheap at H&M. If I get a lot of wear out of them, I'll try to replace them with something higher quality in the future.

Now if you're wondering whether or not I wear tank tops, the answer is yes: but only around the house or within reasonable proximity to a body of water large enough to jump in.

I actually only have one tank top that I wear regularly. I got it at a street market in Laos after several beers and some intense negotiations.

I love the color palette of this tank. I love that it's so worn in and soft. I love how the skinny shoulders make me look more muscular than I really am.

But mostly, I love the memories of this shirt holds. Every time I wear it I feel a tiny urge to crack open a cold Beer Lao and eat some sticky rice.

And that's important. Your clothes should make you feel good!

  1. Did you size up or down with those Birks. Thinking of getting some. Thanks.

  2. Bhavik Sheth says:

    I like the blue dotted everyday shirt by ash and anvil but it is quite expensive.

  3. Ron Krajenbrink says:

    Thanks for showing us the color palette Brock, very helpful, this makes things a lot easier, saving time and money

  4. I joined your website just three weeks ago. I’ve learned a phenomenal amount already! This video, and your examples in particular, have provided a number of new color combos for me to try. I have fairly blue eyes and have almost always gone in the light blue and gray direction. Now I have a whole new style to try. Would that you and your website were available >50 years ago!

    One request: you are slender. I’m pretty barrel chested, 5’6″ 32 ” waist. Would you be able to do a video with individuals built more like me?

    THANK YOU!

  5. Hey Brock,

    Not sure if you already covered it, but one thing I’d love to learn more about is breathable lightweight long leg pants and dress shirts. In most parts of Asia, it’s often considered “scrubby” to wear shorts for most business or social gatherings.

    Even when it’s scorching hot out, you’ll always see people wearing full length pants, nice shoes, and dress shirts on a daily basis. I know there’s options out there, but I’d appreciate your advice on which brands are best at keeping the right look while staying cool.

    Thanks bro
