Stripes.
If Pants are cut from striped goods, the stripe should run parallel with the center line of the angle of 10 deg., both in front and back, though on the forepart it may be located an inch sidewise on the top of the waist; but the back part must have its stripe on that line. This is important to bear in mind, particularly on large pants, which are to be seen often with the stripe running inward or outward. On plain goods it makes no difference where the seams are cut, but on striped goods the forepart should be cut narrow at the side of the thigh, and broad at the side of the bottom in order to run the stripe parallel with the side seam.
It is quite an accomplishment to be able to determine the location of the seams on all kinds of pants without causing them to lose their balance. The top of the front may be cut ¼ full waist for the middle sizes, but the smaller sizes must be cut large enough to make room for the button-hole fly and the pockets. On large-waisted pants, it may save a good deal of piecing to cut the top of the forepart broad, and even as wide as the angle of 7½ deg., and then cut the pockets forward independent of the side seam; but if the material is striped, the stripe will be too crooked over the center of the front. On the front, the stripe may run 1 in. to the side of the top of the center-line on all pants, but on large waists, it may run 2 in. sidewise on top. On the back the stripe must run with the center line.
On a vest the stripes should run at right angles with the pockets, and nearly parallel with the front edge. On all cut-a-way coats, run the stripe with the front plumb line. On the back, run it with the edge of the back tack, and with the edge of the side of the back skirt as well as with the edge of the front skirt, so that the stripes fit to the pleat; but on straight coats, the stripes should run parallel with the front edge, even if the back edge is a trifle bias.
On the side-piece, the stripe should run nearly with the back when they are sewed together, and at the same time the stripe of the side-piece and skirt below should run nearly in the same direction, or as near as possible. On the sleeve, the stripe should run with the front sleeve base.
