The Complete Guide to Dressing Kids for Summer (2026)
Summer is just around the corner, and with it comes the question every parent knows well: how do you dress kids when the temperature starts climbing? Between pool days, outdoor adventures, day camps, and family getaways, kids' warm-weather wardrobes need to be practical, comfortable, and tough enough to keep up with whatever the day brings. Here is our pick of the essential pieces to keep girls and boys stylishly dressed all season long.
Fabrics First: The Number One Priority
Before even thinking about colours or prints, choosing the right fabric makes all the difference when it's hot outside. For summer, we reach for:
- Organic cotton: soft, breathable, and hypoallergenic, it is perfect for sensitive skin. Our organic cotton tees and sets are absolute must-haves for the season.
- Stretch twill: a tightly woven cotton with a touch of elastane that delivers excellent freedom of movement. Ideal for shorts and pants on active kids, it holds its shape wash after wash.
- Lightweight fleece: softer than you might expect for summer, it is perfect for cool evenings or those early camp mornings when the temperature hasn't quite made up its mind.
- Technical fabrics: for sporty days, we go for moisture-wicking materials that dry quickly and are built for kids who never stop moving.
The right fabric means a kid who plays all day without complaining about being hot. And that is priceless.
Summer Wardrobe Essentials
For Boys
The foundation of a great summer for any boy? A solid tee-and-shorts combo. Our boys' tees and tops are designed to move: fun prints, bold colours, soft fabrics. On the bottom, our boys' shorts and pants offer a wide range of motion — whether he is biking, playing soccer, or sliding across the backyard.
The pieces every boy needs in his camp bag or suitcase:
- Organic cotton tees with original prints, easy to mix and match
- Stretch twill shorts that follow his every move without holding him back
- Coordinated pieces from the boys' spring-summer collection to make mornings easier
- Lightweight, breathable boys' athletic wear built for active days
- Boys' swimwear with or without a rashguard for pool and beach days
For Girls
Girls are spoiled for choice! Our girls' dresses are warm-weather staples: easy to throw on, pretty, and lightweight. More adventurous types might prefer our jumpsuits and rompers, perfect for moving freely without a second thought about the outfit.
The must-haves for her summer wardrobe:
- Light casual dresses with sunny prints for family outings
- Coordinated girls' summer sets that make rushed mornings a breeze
- Girls' tees and tops that pair easily with any bottom
- Girls' shorts and pants for active days spent outdoors
- Lightweight summer leggings for structured activities
- Jumpsuits and rompers for an effortless all-in-one look
- Girls' athletic pieces designed to perform as well as they look
Swimwear: Its Own Category Entirely
Summer without swimwear is like ice cream without a cone. Our swimwear collection has something for every kid:
- Boldly printed swim trunks for boys, available with or without a rashguard for extra UV protection
- Girls' swimwear in one-piece and two-piece styles with built-in UPF protection
- Long-sleeve rashguards to extend sun coverage during long days outdoors
One thing to keep in mind: clothing alone is not a substitute for sunscreen. Health Canada's sun safety guidelines recommend applying SPF 30 or higher sunscreen to all exposed areas and reapplying every two hours.
Packing for a Family Trip
Heading out on vacation with the kids this summer? We have got the outfits covered too. Our curated selections of travel-ready clothing — available for girls and for boys — bring together the key pieces to pack so you can leave home without the stress. Handy when it is time to fill the suitcases!
A Few Practical Tips for Parents
- Go for versatility: a pair of shorts that works at the beach and at a patio restaurant is worth its weight in gold. Choose pieces that mix and match easily.
- Layer up: even in summer, evenings can get cool. A light hoodie tucked in the bag is always a smart move.
- Double up on favourites: kids have a gift for getting things dirty the very day they put them on. Having two of the same tee — or close to it — is the mark of a seasoned parent.
- Think light colours: they reflect heat better and help keep kids cooler under the sun.
- Check the care instructions: summer means frequent washing. Go for pieces that are easy to care for and hold their colour after multiple cycles.
Summer Takes Planning — and a Little Spontaneity
We love the idea of a well thought-out warm-weather wardrobe, but we also know kids have their own ideas about style. What matters most is that they feel comfortable enough to live their adventures to the fullest. At Deux par Deux, our Montreal-made pieces are designed with their pace in mind: colourful, durable, and built to last more than one summer.
The season is just getting started. Happy shopping!
