In the context of garments, "loosening" refers to the adjustment or expansion of a specific area or part of the clothing to make it less tight or more comfortable. When a garment is too tight or restrictive, loosening may involve altering the fit by increasing the size, adjusting seams, or modifying certain areas such as the waist, hips, or sleeves. Loosening is a common alteration technique used to improve the comfort and wearability of clothing items.
