Understanding Shoulder and Sleeve Construction
By The Velocity Wear Team
There are three shoulder constructions you will meet on custom apparel: set-in, raglan and drop shoulder. Set-in puts a seam at the natural shoulder point and gives the cleanest chest panel for printing. Raglan runs the seam diagonally from the underarm to the neck, which moves better but eats into the top of your print area. Drop shoulder pushes the seam down the upper arm for a relaxed silhouette, and it changes where a chest logo appears to sit.
Set-In Sleeves and Why They Are the Default
A set-in sleeve is a separate sleeve piece sewn into a curved armhole, with the seam sitting roughly on the bone at the edge of your shoulder. It is the standard for polos, shirts, most tees and structured sweatshirts. It dominates because the seam sits where a shoulder actually ends, so the garment reads as tailored even when it is not.
For decoration it is the friendliest option. The chest and back panels are uninterrupted, the shoulder seam is a reliable measuring anchor, and there is nothing diagonal cutting across the space where a large graphic wants to live. If your design is ambitious in size, a set-in sleeve garment gives you the most room to work with.
The trade-off is mobility. Raising your arms in a set-in sleeve lifts the whole body of the garment, which is why the construction is less common on genuine sportswear.
Raglan and What It Costs You Above the Chest
In a raglan the sleeve continues all the way to the neckline, so the seam runs diagonally across the top of the chest. Baseball tees, many performance tops and a lot of retro-styled sweatshirts use it. The advantage is real: there is no seam sitting on the shoulder joint, the arm rotates freely, and the construction is comfortable under a bag strap.
The cost is print space. The usable chest panel narrows sharply as it rises, so tall artwork runs into the seam. Printing across a raglan seam is possible but rarely looks good, because the seam creates a ridge that the platen cannot flatten and the ink lays down unevenly over it. Plan raglan artwork wider than it is tall, and keep it clear of the diagonal.
Drop Shoulder and the Oversized Look
Drop shoulder moves the seam down onto the upper arm, giving the wide, relaxed line associated with streetwear hoodies and boxy tees. It is a deliberate style choice, and it is not the same thing as ordering a size up.
The catch for decoration is that the wearer's actual shoulder no longer lines up with the garment's shoulder seam. A chest logo positioned by the usual distance from the seam ends up sitting lower on the body than it would on a set-in garment, because the seam itself has moved outwards and the fabric drapes rather than sits. If you are ordering drop shoulder pieces alongside conventional ones for the same team, treat them as two different placement briefs, not one.
- Set-in: cleanest print panel, best measuring anchor, most tailored appearance, least freedom of arm movement.
- Raglan: excellent movement, comfortable under straps, noticeably reduced vertical print space and a seam that resists printing.
- Drop shoulder: relaxed contemporary silhouette, generous chest and back panels, but placement measured from the seam sits lower on the body.
- Set-in with shoulder taping: a narrow tape sewn along the shoulder seam that stops it stretching over time, worth specifying on anything that gets heavy wear.
- Armhole depth matters independently of all three: a deep armhole feels roomy but restricts arm lift more than people expect.
“"A raglan is not a crew neck with the seams moved. It is a different canvas, and a fair amount of the artwork sent for one was drawn for the other."”
Shoulder Taping and Seam Life
Look inside a well made sweatshirt or tee and you will often find a narrow strip of fabric sewn along the inside of the shoulder seam and sometimes around the back neck. That is taping. Its job is to take the load off a seam that is stretched every time the garment is pulled over a head or lifted off a hanger.
It is a small detail with a long payoff. Untaped shoulders on a garment worn daily gradually widen, the neckline goes slack, and the whole thing starts to look tired even though the fabric is fine. For uniform and workwear, where the same garment is worn several days a week for a year or more, taping is one of the highest-value details on the spec.
Sleeves, Cuffs and Where They End
Sleeve length grades far less between sizes than chest does, so a garment that fits your chest may still have sleeves that read short or long. On long sleeves, the cuff finish matters as much as the length: a ribbed cuff sits at the wrist and stays there, while a hemmed sleeve slides. If you are embroidering a sleeve, a hemmed sleeve is easier to hoop cleanly than one with a rib.
Deciding Construction Before Artwork
The practical order of operations is construction first, artwork second. Choose the garment shape that suits how it will be worn, then design into the space that shape leaves you. Doing it the other way round is how a design that looked confident on screen ends up squeezed above a raglan seam.
Velocity Wear supplies from a 20-piece minimum per order with sizes mixed freely, and the free Design Studio shows how artwork interacts with the seams before you approve anything. Screen printing and embroidery typically run around 10 to 15 working days from artwork approval, with complex jobs nearer 15 to 20.
