A client would like to know if a roll collar can be designed and sewn as two pieces instead of the traditional one.  Here is our answer.

Traditionally, a roll collar in its various forms (shirt, convertible, sports, etc.) is designed for a front opening bodice.  For those who prefer a back opening instead of a front opening for modesty reasons, they can re-design the roll collar to maintain its roll yet cut in two pieces.  The trick is to re-attach the roll collar at the Center Back below the roll line with mechanisms such as hooks-and-eyes, button-and-loop, etc.

One-piece Traditional Roll Collar

Here is a sample of a Traditional Full Roll Collar design, which you can download from My Sloper (Collar, Blouse, Dress).

Two-piece Traditional Roll Collar

To convert the one-piece roll collar to two pieces, simply add seam allowance at the Center Back (CB). Re-write the cutting instructions to have 4 pieces instead of 2.

Assembly

Sew your garment according to its instructions.  With a back-zipper opening, sew the back zipper before attaching the collars.  Attach the collars at the neckline and follow these simple instructions.

Model

We took the liberty of creating a model demonstrating that this can be done.

Two-piece Roll Collar With Back Opening

The technique of using hooks-and-eyes can be applied to other collars as well, including our Cowl Collar.  See below.
