Fastenings for undergarments (Figs. 99-101).

Buttonholes and buttons are the best fastenings for most undergarments because they launder well, wear well, and may be an interesting part of the design of the closing of a garment.

Single-bar buttonholes are fan-shaped at one end and have a bar finish at the other. They are generally used where there is a strain; the button rests in the fan-shaped, or rounded, end of the buttonhole.

Double-bar buttonholes have the bar finish at both ends. They are generally placed vertically in the garment and are used where there is not much strain and where the button slips up and down in the buttonhole.

To sew on buttons, the stitches should be taken over a pin placed on the top of the button. The pin should then be removed and the thread wound several times around the stitches between the button and the garment to make a thread neck or shank which holds the button up from the material, making room for the buttonhole and giving the fastening greater strength.
