This long sleeve hoodie t-shirt delivers a bold faux two-piece look by combining a short-sleeve hooded top with a striped long-sleeve underlayer — all in one seamlessly constructed garment. The front is decorated with a large Union Jack motif rendered entirely in heat-set rhinestones, giving the piece an eye-catching, high-craft finish. The hood and sleeves are lined and constructed in a black-and-grey horizontal stripe fabric, creating a sharp contrast against the solid body. Available in Black and Heather Grey.
Product Highlights
Faux layered construction — short-sleeve hooded body over a striped long-sleeve base, built as a single piece
Large rhinestone Union Jack graphic across the full chest front
Striped hood lining and long sleeves in black and grey horizontal stripe fabric
Clean, plain back panel for a balanced, wearable silhouette
Available in Black and Heather Grey colorways
Relaxed, slightly oversized fit suitable for casual and streetwear styling
Fit & Styling
The silhouette is relaxed and slightly boxy through the body, with the layered sleeve detail adding visual length and dimension. It fits true to size with a generous chest measurement — size M measures 120 cm chest and 68 cm body length. Pair with slim-fit trousers or joggers to balance the volume of the top. The rhinestone graphic and stripe contrast make this piece a standalone statement; keep the rest of the outfit minimal. Best worn as a casual streetwear top for everyday outings, social occasions, or relaxed weekend wear.
Product Details
Fabric composition is approximately 95% Cotton, 5% Elastane for the main body panels, with the striped sleeve and hood sections constructed in a cotton-blend stripe jersey. The rhinestone embellishment is applied via heat-transfer setting across the Union Jack design on the chest. The garment features a pullover construction with no zip or buttons. Hood is unlined at the crown and open at the face. Available in sizes M, L, and XL.

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.
