A tuck is a fold that’s been stitched in place. A very thin fold is referred to as a pintuck. Pintucks are a versatile detail you can add to the simplest of garment designs.
You can have as many or as few tucks as you like and add them anywhere on the garment that doesn’t interfere with darts. They can go in just about any direction you like. In fact you could make an entire garment of tucks! It might be tedious sewing up all those tucks, though. Many sewing machines have pintuck feet to make sewing them easier. Have you had experience sewing tucks? Do you have any tricks you use? What are some ideas these images give you for future projects? I think they’d look great on a shirt or a dress bodice in a solid color so you can really see the detail.
