Q: My husband and I have entered the cross-country Great American Race with our 1914 Model T Speedster. The race starts in Los Angeles and ends in New York City. We will need cool racing outfits typical of 1914. I am 5 foot 9 and wear size 16, and my husband is 6 foot 3. I am a very good seamstress and could make our outfits. Do you know of any patterns?--M.L.B. A: The authentic Model T duster coats illustrated here should be ideal for your travels. Although the originals were made in a tightly woven linen called "duck goods," you will be better protected from the elements if you weatherproof your linen fabric with Scotchgard. The woman's duster is Folkwear's Style 230 and sells for $7 plus $2 postage. The people at Folkwear say that the coat is close-fitting and runs rather narrow. It is available in sizes 8 to 16, so you may have to adjust the pattern to accommodate whatever you wear underneath. If the patterns are not available in your local fabric store, you can order directly from Folkwear, P.O. Box 3798, San Rafael, Calif. 94912. We show your duster with an authentic chiffon-wrapped hat, but alas, we could not find the hat. The gentleman's car duster is Style 200 from Past Patterns, 2017 Eastern S.E., Grand Rapids, Mich. 49507. Past Patterns cautions that this pattern has no step-by-step illustrations and suggests testing the pattern in a muslin first to make sure that the coat is roomy enough to wear over clothing. This duster pattern from about 1910 is priced at $10, postpaid, and comes in chest sizes 34 to 40. Behind the large pockets are overlapping slits that allow handy access to trouser pockets underneath. The double-breasted front closing also is overlapped, and the cuffless sleeves are longer than those used in today's patterns.
