What are the main differences between a sleeveless tank top versus a top with sleeves? What do you need to do when you want to add a sleeve to a sleeveless pattern?

1. Sleeveless tops usually have a lower armhole depth between 1/4”–1/2”.
2. The shoulder width, across front, and across back are usually smaller on a sleeveless top.
3. The necklines will vary per style.

How to Add Sleeves to a Sleeveless Pattern

If you want to add a sleeve to a sleeveless top, you will need to raise the armhole and fill in the shoulder area.

To create the sleeve:

1. Mark a straight line for the center of the sleeve
2. Mark the bicep width plus ease
3. Apply the sleeve cap height and width as shown in the previous methods

Ensure the sleeve is 1/4”–3/8” larger than the armhole for woven fabrics.

For knit fabrics, the armhole and sleeve measurements can be the same.
