Pick the right size. Use a tee you already own and our garment measurement chart to pick your size in under five minutes.
Choosing an oversized tee should feel exciting, not confusing. At LUCSUM, we design every piece in our T-Shirts collection with deliberate proportions — but the best fit is still personal. This guide walks you through how to find a silhouette that feels relaxed, looks intentional, and works with the way you actually dress.
Start with measurements, not size labels
Size names vary between brands. A medium at one label might match a large at another. That is why our Size & Fit page lists chest width, body length, and shoulder width for every garment. Before you order, lay a favourite tee flat, measure across the chest from armpit to armpit, and compare those numbers to our size chart.
If you are between sizes, think about the look you want. A true-to-chart LUCSUM size gives a clean oversized silhouette — relaxed but balanced. Sizing up adds more drape and length for a bolder streetwear shape. Neither is wrong; it depends on your proportions and styling preferences.
Shoulders set the tone
In an oversized tee, the shoulder seam typically sits lower than a classic fit — that is the dropped-shoulder look. It should still create a clean line across your upper body rather than hanging halfway down your arm. Check product photos and measurements to see where the seam lands relative to your own shoulder width.
Our Contrast Panel tee and Raglan Baseball tee use different construction at the shoulder, which changes how the fit reads. Contrast panel styles offer a classic dropped shoulder, while raglan sleeves create a smoother diagonal line — worth considering if you prefer a softer shoulder profile.
Body width and length work together
Width alone does not define oversized. A wide body with a short length can feel boxy and cropped; extra width paired with a longer hem creates the flowing streetwear silhouette most people picture. Look at both measurements together when comparing styles.
For a more dramatic look, explore pieces in our New Arrivals collection and consider sizing up one level. For everyday rotation pieces, true-to-size often delivers the sweet spot — enough room to move without excess fabric bunching at the waist.
Styling changes how fit reads
The rest of your outfit affects how oversized looks. Wide-leg trousers balance a relaxed top; a structured jacket over a roomy tee creates contrast. If you are wearing an oversized graphic from our Graphic Tees collection, keep the bottom half cleaner so the print remains the focal point.
Essentials from LUCSUM Essentials — contrast panels, raglan cuts, branded tape — are designed to anchor a wardrobe. They pair easily with denim, cargos, or shorts, making them ideal starting points if you are building your first oversized rotation.
When in doubt, reach out
Fit is personal, and we would rather you feel confident before you buy. Use our size chart, compare flat measurements, and remember that LUCSUM pieces are cut for oversized streetwear — not slim tailoring. For fabric care that keeps your fit consistent wash after wash, see our Care Guide.
The right fit is the one that makes you stop adjusting your clothes and start living in them.
