Although summer is a welcome reprieve from rainy and snowy weather, hot weather brings its own set of style challenges. Once temperatures rise to 80-degree weather and up, choosing the right outfit that looks and feels good in the heat can be difficult. It all comes down to the right fabrics, cuts, and accessories.

If youâre looking for some hot weather style inspiration read on. We've put together a summer fabric and style guide that will make dressing in 80-degree (27 degree Celsius) weather a breeze.
Fabric for function
In hot weather, heavy or synthetic fabrics like nylon or acrylic can make the heat even more unbearable. The key to looking and staying cool in 80-degree weather is choosing lightweight, breathable, natural fabrics. Weâve put together a list of summer fabrics to look out for below.
Fabric Type |
When to Wear |
Cotton |
Cotton is a staple in most clothing items, and itâs perfect for day-to-day wear. Contrary to what most think,100% cotton is not breathable, so in hot weather, choose a cotton blend with Lycra or Tencel. |
Polyblends |
Polyester by itself is not a great choice for hot weather as it's not very breathable. Polyblends, however, are ideal for the heat since theyâre lightweight, breathable and moisture-wickingâwhich is also why they're a staple in activewear. |
Tencel |
Tencel is the better alternative to cottonâitâs much more absorbent and sustainably sourced! You can find it in plenty of pants and t-shirts. Tencel is lightweight, so garments made with it tend to be flowyâthe perfect choice for 80-degree weather. |
Merino Wool |
While traditional wool is a hot weather no-no, Merino wool is actually lightweight enough to wear running! Itâs breathable and has great moisture-wicking capabilities. If you prefer the comfort of a sweater even in the heat, we recommend reaching for Merino wool. |
Chambray |
Chambray is a lighter weight alternative to denim. Depending on the threadcount of the fabric, chambray button downs are professional enough for the office or in lower thread counts are more casual and rugged-looking. |
Linen |
Linen, derived from the flax plant, is the second strongest material after silk and is highly absorbent. Due to its natural fibers, itâs lightweight and breathable. |
Picking âCoolâ Clothes
Knowing which fabrics are best for the 80-degree weather is a step in the right direction to staying cool. Letâs look at the elements of great hot weather fashion from head to toe.
Tops
In 80-degree weather, removable layers are your friend! A lightweight jacket or sweater is ideal for warm weather activities like cycling, rock climbing, or hiking. Make sure your base layer is made from a breathable, moisture-wicking fabric like Tencel or a polyblend.
Bottoms
In the summer heat, wear loose or cropped bottoms to stay cool. If you prefer longer pants, check out our No Sweat line or our Performance Denim Lite collection with professional pants you can wear in the heat yet feel as comfortable as your favourite sweats. You can also pair a flowy skirt or pair of shorts with a staple item like a crisp white t-shirt.
Undergarments
How could we exclude undergarments? Although theyâre hidden away, the right undergarments certainly affect our comfort level in hot, humid weather.
For women, sports bras and bralettes are ideal for the hot weather as theyâre usually made with nylon and spandex for breathability without the discomfort of underwires.
In terms of underwear, material is everything. The wrong material can trap heat and lead to bacteria growth and odor. BN3THâs pouch underwear are made with sustainably sourced Tencel Modal for breathability and provide extra support. Their unisex underwear comes in vibrant designs for men, women and anyone in between.
Accessories
The most important accessory on hot, sunny days is a hat to protect your head from direct sunlight. And while not exactly an accessory, sunscreen is also vital in 80-degree weather. Even if youâre wearing a hat, don't skip it!
Shoes
In most situations, sandals or lightweight running shoes will suit 80-degree weather. Avoid heavy boots unless required for work or if you're an avid hiker.
Summer style for every situation

Around the Office
Usually, hot weather calls for casual, loose-fitting clothes, but this doesnât always work for the office. You canât show up in cut-offs but you can still be comfortable! Hereâs how:
For a feminine look in hot weather, a lightweight dress or skirt (made with Tencel or linen) is a great option for staying cool and comfortable. A colorful flowy romper or jumpsuit is another option, as they range from casual to professional in design. For the office, pair the Performance Denim Jumpsuit with a blazer and black sneakers or oxfords. If youâd like something lightweight, try a linen or chiffon jumpsuit with flats or sandals.
Of course, a dress and skirt are not the preference of all women, so we also suggest dressing up a pair of jeans or joggers. The Live Free High Rise Jogger in neutral thyme can take a white blouse and black blazer to the next level. Or try the No Sweat Denim High Rise Wide Leg for an elevated Tencel-heavy full length option.
If your fashion sense leans toward the masculine, you can also opt for lightweight trousers or jeans on casual Friday! The Weightless Poplin AC Pants are slightly cropped with a dark wash for business casual dress codes yet the comfort of jeans. For more formal office settings, a light-coloured linen suit is the perfect choice in 80-degree weather.
Happy Hour
If youâre coming from the office, you can dress down your work clothing by dropping the blazer or suit coat. If youâre planning for a patio, wear light colours to reflect the sunâs rays.
For a feminine look, grab a pair of loose or flowy pants like the Performance Denim Lite Pleated Pant with a sleeveless blouse or bodysuit.
For a masculine look, opt for a pair of shorts in a bright colourâlike the Live Free Journey Shorts in Dark Red. Pair them with a button down that has the same colour in the pattern for subtle cohesion in your outfit! Or if you're more of a jeans guy, try the Performance Denim Lite Slim Straight for lightweight jeans you can wear even on the hottest of days.
Backyard Barbecue

Hanging with friends and family grilling tasty treats is one of the best things about 80-degree weather!
If youâd rather enjoy the BBQ than cook it, try the Performance Denim Short with a button down and a t-shirt underneath. Our Air Flow Pique Tee has great breathability thanks to the pique weave.
For a more feminine look, a cropped tee is a versatile item perfect for a backyard barbecue. The PurePima Dolman Tee comes in black and whiteâcolours that can match whatever shorts or skirt you want to pair it with!
Summer Wedding
Summer weddings are a blast, but stuffy suits and dresses can make long ceremonies even more unbearable.
Linen suits are the answer! Men and women can rock a linen suit at weddings all summer long. Theyâre lightweight and breathable so you can hit the dance floor (or the buffet) without any concern about overheating. If linen isn't the vibe, looks for pants and shirts that include moisture-wicking properties and extra breathability to help you feel cool.
For more of a feminine look, a lightweight dress made of chiffon or silk will keep you comfortable all night long.
Just remember to express your style, choose clothes for the formality of the occasion, and skip the white/cream colours.
Hiking
Whether it's a hiking date or solo, hikes can be a great form of exercise and a way to connect with nature. Just make sure to choose one with adequate shade and to avoid the hottest hours of the day.
Usually, long pants and a long sleeved shirt are best to protect your skin from brush, branches, and bugs. If itâs too hot though, try to pick a trail where brush is minimal so you can wear a t-shirt and shorts. The Live Free Journey Short has a long inseam which will protect you from chafing during your hike.
