The strong shoulder is a silhouette that seems to be here for a while. This classic sleeve is stylish and easy to draft.

The square sleeve cap is one of those Forties styles that makes appearances every now and then. It introduces design into the cap of the sleeve.

Its mitered, box-like appearance extends the shoulder line into the sleeve cap and adds to the sleeve bicep, which makes it a good candidate for fitting a jacket, where a small armhole is desired but the wearer has a developed bicep, and needs more room in that area of the sleeve. The miter helps finesse any extra cap ease that would be added to accommodate the fuller bicep.

 

A design advantage to this sleeve for those who have developed biceps:  When the bicep is full, generally there is a full bust as well, which makes the shoulders appear narrow in comparison. This draws the eyes to bust level, making the eyes track horizontally.

Having a square sleeve cap adds width higher up on the body. They draw the eyes upward to the shoulder, so the observer's attention goes to the face, which is what we want.

 

 

Start developing this sleeve pattern by using the basic shirt-sleeve draft.

I would like to make this sleeve; in fact, I have the Style ARc pattern which incorporates such a sleeve. It appears that the bodice should have some adjustment for this sleeve, too. It does not appear to sit in the same armscye as a 'regular' sleeve. Help!

If I'm wrong, how do I modify my bodice's armscye so my sleeve sits in farther?

Thanks-

Teresa

To Rit: You do in deed want to add seam allowances to the draft--I always show a drafting process with just finished stitching lines for clarity.

This sleeve will fit exactly into the same armhole, as you don't change the circumference of the sleeve armhole in the draft.

SewingSadie SewingSadie writes: Great Tutorial! I really appreciate your "objective view" tip, ie: WHY you want to bring the eyes up from the bust area to the face, and HOW to do so. FYI: I would love to see a picture of a finished cap sleeve on a dress.........!
Most Sincerely, SewingSadie

vivienz vivienz writes: Great tutorial. I have a jacket pattern that has slightly puffed/pleated sleeve heads that are above the shoulder line, and I don't really care for them so I may well substitute these. As a pear shape, the extra shoulder width will help with overall balance of my silhouette.

rlt rlt writes: I like the look of this sleeve. You did not mention anything about Seam Allowances on the extension for the dart/pleats in the tutorial. Also, will this sleeve fit into the original armhole or does an adjustment need to be made to it as well?

Thank you
