Button-Up Shirts

Button-Up Shirts at Seakoff

This is the full button-up and overshirt lineup — plaid flannels, colorblock short-sleeves, and graphic-print shirts all built to either stand alone or layer open over a tee. It is one of the more versatile categories in the store because the styling shifts depending on how you wear it.

For the plaid-specific versions, see Plaid Shirts. For jacket-weight overshirts, check Plaid Jacket Shirts.

  • Buttoned or Open — Which Way Should You Wear It?

    Buttoned up, these read closer to a casual shirt; worn open over a plain tee, they function more like a light layering jacket. Both are intentional ways to wear the same piece depending on the weather and look.

    What Pairs Well With a Button-Up?

    Under a bomber jacket for extra layering in cooler weather, or on its own with baggy jeans in warmer months.

  • Q: Are these shirts fitted or relaxed?
    A: Most run in a relaxed, slightly oversized cut suited to layering — check individual listings for exact measurements.
