The cost of a garment is basically made up of 3 things: the material, the time of the seam (the salary of the seamstress) and the additional materials. Logically, the smaller the product, the lower the price, because less material is used and less sewn. But reality is not always the case. For example, when compared to a large adult t-shirt and a small baby bodysuit, it takes much more time to sew that little bodysuit, put it on edges and fasten it. Yes, it consumes less, but it does not balance the price of the seam. Sewing on small details, sleeves, ribs requires quite a bit of fingering, pecking and precision. As a result, it also takes more time to produce the product.
