A sharp take on the classic long-sleeve top, this mens henley t-shirt long sleeve style combines a relaxed crew-adjacent neckline with a half-placket fastened by polished silver metal snap buttons. Two buttoned chest patch pockets and decorative shoulder epaulette buttons give the shirt a utilitarian, high-street edge that works equally well dressed up or down.
Product Highlights
Half-placket henley opening with silver-tone metal snap buttons running from collar to mid-chest
Two buttoned chest patch pockets for a workwear-inspired aesthetic
Shoulder epaulette detail with matching metal buttons for added visual structure
Ribbed crew neckline for a clean, comfortable finish
Available in Black, White, and Dark Grey — versatile solids that pair with any bottom
Long sleeves with ribbed cuffs for a neat, polished look
Fit & Styling
This shirt is cut in a relaxed regular fit with a slightly longer hem, making it easy to wear tucked or untucked. The structured pocket placement and metal hardware keep the silhouette looking intentional rather than casual. Pair it with slim chinos or dark jeans for a smart-casual outfit, or layer it under an open overshirt for a streetwear-influenced look. The solid colorways make it a versatile layering piece across seasons. Refer to the size chart: size M measures 66 cm in length, 106 cm chest, 49.5 cm shoulder width, and 59 cm sleeve length.
Product Details
Constructed from a medium-weight cotton-blend jersey — approximately 95% Cotton, 5% Elastane — the fabric offers a smooth hand feel with just enough stretch for all-day wear. The silver metal buttons are consistent across the placket, chest pockets, and shoulder epaulettes for a cohesive hardware finish. Available in sizes M through XXL.

How to Find Your Perfect Size — Every Time
How to Find Your Perfect Size — Every Time
Struggling to pick a size online? Here's a simple trick: instead of guessing, use a piece of clothing you already own — and love the fit of — as your reference point.
Step 1: Pick Your Reference Item Think of a T-shirt you've bought before that fit you perfectly. Find that order and pull up its size chart.
Step 2: Focus on Two Key Measurements For streetwear-style tees, two numbers matter most:
Chest width— too narrow and it'll feel tight
Length— too long and it'll look sloppy
💡 Tip:Size charts sometimes list "Chest" as theflat-lay widthinstead of the full circumference. Here's how to tell the difference:
Large number(e.g., 49in / 124cm+) → likely the actual chest circumference
Small number(e.g., 24in / 62cm) → likely the flat width (garment laid flat and measured edge to edge)
Step 3: Note Your Ideal Numbers Write down the chest and length measurements from your best-fitting shirt. Care about sleeve length or shoulder width too? Note those down as well.
Step 4: Match to Our Size Chart Now check Seakoff's size chart and pick the size whose measurements are closest to your notes. That's it — no more guessing.
Works for Everything This same method applies to hoodies, sweaters, jackets, and more. Do it once, and you'll be able to shop confidently, anywhere — every time.
