How to Cut Sleeves Off Shirts: T-Shirts, Flannels and Denim

You only need a few tools: sharp fabric scissors, chalk or a washable marker, a measuring tape and a flat surface. Dull kitchen scissors chew fabric and leave ragged edges.

There are four main ways to cut sleeves. Here’s how they compare.

Before picking a cut, check what the shirt is made of. The fabric matters more than the style you choose.

That one fact decides how much finishing work you need. Knit tees can be cut and worn; woven shirts need a hem or a planned frayed edge.

Shortening sleeves gives a tee a more fitted, muscular look. It works best on sleeves that hang past the middle of your bicep.

Because jersey knit doesn’t fray, you can leave the new edge raw. It will curl slightly after washing, which looks soft and casual.

Trim in small amounts and try the tee on between cuts. Here’s the difference a good trim makes.

Removing the sleeves entirely turns a tee into a sleeveless shirt. Cutting just outside the seam keeps the shoulder neat; cutting inside the seam makes a wider, more relaxed armhole.

For a muscle tee, cut a little lower under the arm. That opens the armhole for more movement in the gym.

The armhole depth is where most people go wrong, so take it slowly.

Cut less than you think you need. You can always take more off, but you can’t put it back.

Flannel and button-up shirts are woven, so their cut edges fray. You’ll need to hem them or deliberately fray them for a rugged look.

Leave about an inch of extra fabric beyond the seam if you plan to hem. That gives you enough to fold under neatly.

A hand-stitched hem takes longer but looks neater than a rushed machine line. Press the fold with an iron first so it stays put while you sew.

Skip It If the Shirt Is Expensive or Tailored

Cutting a good dress shirt or tailored flannel ruins its value. Practise on an old or second-hand shirt first.

A denim jacket with the sleeves cut off makes a classic rugged vest. Denim is thick and woven, so it frays nicely when washed.

Cut just outside the sleeve seam to keep the armhole’s shape. The seam itself helps stop the fray from creeping too far into the body.

Each wash loosens a few more threads, so the fray grows over time. If you want to limit it, stitch a line before the first wash.

Sweatshirts are knit, so they don’t fray much when cut. You can shorten them to short sleeves or cut them off entirely for a sleeveless gym top.

Cut below the ribbed cuffs to shorten the sleeves, or along the seam to remove them. Thick fleece edges stay neat without hemming.

Cut a little wider than you think, because thick fleece is snug once the cuff is gone. Try it on before you trim further.

Knit edges can be left raw, but woven edges need a finish. A neat hem looks cleanest, while a deliberate fray looks rugged.

Seamstress Doina Alexei calls pinking shears “a great technique both functionally and aesthetically,” but notes the method may not hold up to long-term wear and washing on apparel. A sewn hem is the most durable option for clothes you wash often.

Doina Alexei also warns that iron-on hem tape “can add some stiffness” and suits crafts better than clothing. For t-shirts, gently stretching the cut edge helps it roll into a soft, clean finish.

Most ruined cut-offs come from cutting both layers at once, rushing, and going too deep. A little care avoids all three.

Cutting Through Both Layers at Once:

Cutting the front and back together often makes uneven, slanted edges. Cut one layer at a time, following your chalk line.

Another mistake is not matching the sleeves. Always fold the shirt in half and use the first cut side as a template for the second.

Work on a hard, flat surface and keep your fingers clear of the blades. Sharp scissors are safer than dull ones because they need less force.
