What to Wear in 100-Degree Weather If You Still Want to Look Chic
It's hard not to notice that we are having an exceptionally hot summer. Unless you're one of the lucky few who have been able to escape to the countryside for a much-needed reprieve, you've likely joined the masses in their desperate search for cool beverages, shade, and water in any form. City fountains have become watering holes, iced coffee has become a food group, and awnings provide a break from the unrelenting sun. In this scorching summer heat, even though the rule seems to be the fewer clothes the better, unfortunately, many of us don't have the luxury of neglecting our duties, throwing on a bikini, and heading for the nearest pool. We have work to do, meetings to attend, friends to meet for drinks, and we need outfits that will carry us from A to B without subjecting us to heat exhaustion.
The fact remains that less is better, however, so we've pulled together six outfits that will beat the heat. Continue on for the ultimate summer inspo from our favorite fashion girls and figure out what to wear in 100-degree weather.
The Easy White Dress
When temperatures are soaring, you really can't go wrong with a breezy white dress. I always have one ready to go for moments like this. It's one of those rare outfits that require virtually no styling to look chic, especially when paired with simple flats, sunglasses, and a great bag.
The Matching Set
A long, loose top might sound counterintuitive for a 100-degree day, but the right fabric and silhouette can actually make for an incredibly chic warm-weather look. Opt for airy cotton or linen styles that skim the body rather than cling to it. Then pair it with loose, lightweight pants for an outfit that feels polished without being restrictive. Modest and chic.
The Nightie
Take inspiration from the sleepwear trend and embrace an ultra-loose, nightgown-inspired dress. The barely there silhouette is ideal for hot summer evenings, while a pair of sleek flats and a structured bag keep the look from feeling too casual.
The Hot Pants
If you're going to wear tiny shorts, you might as well have fun with them. A crochet tank and short shorts make for an easy vacation-ready combination that feels especially good when you want an outfit with minimal fabric and maximum personality.
The Lace Shorts
Lean into the fun side of summer with a pretty, barely there top and delicate lace shorts. The combination feels feminine and fashion-forward while still leaving plenty of room for airflow—exactly what you want when it's too hot for anything complicated.
The Overalls
For a beach day, pool outing, or particularly casual summer afternoon, swap a traditional top for your favorite bikini underneath a pair of lightweight overalls. It's an easy way to make swimwear feel like a real outfit while keeping things as cool as possible. I just got a pair and plan on trying this out myself sometime soon.
The Tank and Shorts
Sometimes the simplest formula really is the best. Give the classic shorts-and-tank combination a fashion-editor spin by choosing elevated versions of both—think tailored shorts, a fitted ribbed tank, and sophisticated accessories.
The Romper
The one-and-done outfit is especially appealing when it's 100ºF out. A lightweight romper gives you the ease of a dress while still feeling a little more pulled together and practical for everything from errands to lunch plans.
