A Breton stripe without a nautical costume

Start with the stripe you actually like

A Breton-style top can have narrow stripes, broader bands, a boat-like neckline or an ordinary crew neck. Those differences affect the outfit more than the label does. Try the neckline first: a wide opening may show an undershirt or sit differently under a jacket. If you prefer a closer neck, there is no reason to accept an uncomfortable shape for the sake of a recognisable style.

Look at where the pattern begins and ends. A plain upper panel changes the visual emphasis, while stripes continuing to the neckline create a more continuous pattern. Neither needs a rule about body shape. Compare the actual tops with familiar trousers and choose the balance you prefer.

Use ordinary trousers

Dark straight jeans are a simple partner. Olive chinos or plain charcoal trousers move the top away from an obvious seaside association. White trousers can also work, but they strengthen that association; add deck shoes and a conspicuous rope detail and the theme becomes more explicit. Decide how much of that story you want rather than following every related cue.

The width of the top matters alongside the trouser leg. A boxy striped shirt can sit comfortably over a straighter or fuller trouser. A close version may look different when tucked. Test the hem in both positions if its length allows, and avoid forcing a bulky fold under a narrow waistband.

Add one quiet outer layer

A plain overshirt or coat gives the stripes a frame. Keep its colour uncomplicated at first so you can judge the pattern clearly. Navy is familiar, but brown, olive and grey can also work. A second pattern is possible; it simply requires more attention to scale and contrast than a plain jacket.

Finish with shoes you already wear rather than buying a themed pair. Trainers, loafers or simple boots can each change the mood. The useful question is whether the striped top belongs in your regular rotation. If you can only imagine it in one highly specific holiday scene, try a less distinctive neckline or colour combination before deciding that stripes are not for you.
