Whether you call her a sewist, a sew-er, a seamstress, or something else, you may occasionally see her out looking at clothing in the store. She is easy to spot. Just look for these signs.
1.) She turns all the clothes inside out. While most of the shoppers will pick up an item of clothing and hold it out in front of them, or maybe drape it over their bodies, imagining how it might look on them, the sewist will try to turn the item inside out so that she can see the inside of it. She is looking at the seams and analyzing the construction. She wants to know how it was made and if it was made well.
2) She uses oddly specific terminology. While others might point to "that blue shirt over there," she will refer to the "bias-cut blouse with the neckline placket and the welt pocket." She might even use a word like "garment."
3) She is shopping in the big men's section for her baby boy. Because all clothing is really just fabric ready to be cut and sewn into something else.
4) She pulls out her fabric tape measure. This one is a dead giveaway. She might be discrete about it, but if you see her pull out that fabric tape measure and start measuring the dimensions of the garments, you know she's a sewist.
Have you done any of these things? Do you know someone who does? If you sew, and you notice someone else doing these things at the store, maybe you should say hi!
