9 Square Pants Outfit Ideas with Striped Shirts and Navy Jackets

There’s something effortlessly refined about mixing structured tailoring with classic prints. Striped shirts and navy jackets bring timeless charm to modern silhouettes, while square pants offer a bold yet versatile base. With their clean lines and flattering cuts, these pants serve as the anchor for building layered, intentional looks. The following combinations highlight how to elevate square pants outfit ideas with the addition of navy tones and crisp stripes, creating outfits that feel both polished and relaxed.

Square pants outfit ideas featuring black and white striped tees and cropped navy jackets

Square pants get an effortlessly cool update when styled with a black and white striped tee. This look leans more casual but still delivers strong style. The cropped navy jacket adds just the right amount of layering without overwhelming the simplicity of the outfit. Square pants keep the foundation modern and relaxed, especially when cut in a heavier fabric like twill or wool blend.

Pair this with chunky sneakers to underline the casual tone and make it perfect for running errands, museum strolls, or weekend brunch. A small crossbody bag in neutral or earth tones complements the navy and ties the outfit together.

What makes this pairing stand out among square pants outfit ideas is its balance of comfort and design. The cropped jacket adds visual interest, while the monochrome stripe pattern acts as a chic anchor. To complete the look, a striped tee with a slightly boxy cut works best—like this crew neck cotton tee that blends softness with shape.

The resulting outfit feels youthful but refined, and it’s a wonderful go-to when you want to keep things simple without compromising on style.

Square pants outfit ideas with pastel striped button-downs and oversized navy coats

Pastel stripes introduce a softer tone to an otherwise tailored ensemble. Square pants in crisp white, when paired with a flowing, oversized button-down in muted pinks, lavenders, or mint, lend a breezy charm. The addition of a long navy coat, especially one with structure and weight, provides contrast while tying everything together.

This combination is ideal for transitional seasons when layering is key. You can opt for loafers or ballet flats depending on your comfort, and even a scarf in complementary tones can add a playful twist. The white square pants bring in brightness and work beautifully against both the navy and pastel palette.

For accessories, stay in the soft color family—powder blue or lilac bags, or light silver jewelry. The oversized coat acts as a statement piece while giving off an elegant, slightly androgynous vibe. To get started on the right shirt, this pastel striped button-up shirt is lightweight and perfect for layering under a structured coat.

This look stands apart in the world of square pants outfit ideas thanks to its contrast in volume and texture. It’s soft, composed, and undeniably stylish.

Stripes and navy outerwear bring new life to classic tailoring, especially when anchored by the clean silhouette of square pants. Whether the mood calls for fitted precision, playful volume, or relaxed ease, these combinations prove that even the most timeless pieces can be reimagined with a modern edge. Square pants outfit ideas shine brightest when they’re personalized, and striped shirts with navy jackets offer the perfect starting point for confident, repeat-worthy looks.
