    ONE-PIECE OUTFITS FOR BABY BOY

    The easiest outfits for baby boy? One-pieces, of course! Whether it’s a tank-style baby one-piece for hot summer days or a sherpa-lined hooded one-piece for extra chilly winter afternoons, there’s a perfect outfit that will have your baby boy ready in a snap (or a zip).

    Spring and Summer Outfits

    Warm weather calls for short sleeves and easy dressing. An easy baby boy romper is perfect for hot days. Try polo-style baby one-pieces with little collars and button-fronts. Or opt for a tank top style romper to maximize on the sunny weather. In spring, try pairing their one-piece outfit with a little jacket or cardigan for chilly mornings. Easy layers help keep your baby boy comfy no matter what the day brings.

    Baby boy denim shortalls are another easy dressing option for warmer months. Wear on their own or pair with a graphic bodysuit. Don’t forget the camera. Shortall moments are simply picture perfect.

    Psst... our one-pieces come in sets, too! With matching hats or even shoes, baby one-piece outfit sets make dressing and outfitting extra easy on parents.

    Fall and Winter Outfits

    Chillier weather calls for thicker fabrics and extra layers. Long-sleeve baby boy one-pieces are wardrobe staples. Try options that have fleece or sherpa lining for extra warmth. Hooded styles are also great choices to keep baby’s head and ear protected from the wind.

    Footed baby one-pieces are perfect for playtime and nap time. Lots of our footed one-pieces are made with two-way zippers, so dressing and diapering is super-fast and fuss-free. Plus, each zippered style features a snap tab that covers zippers to protect tiny chins.

    No matter the season, babyGap has an easy dressing one-piece for your baby boy. Don’t forget to tag us on social media to show us your baby’s new fit.
