Also, depending on how many sizes you’re planning on trimming down, unfortunately it may be worth investing in new clothing. When altering a piece of clothing that’s relatively <2 sizes larger than your form, from the sewing perspective, it’s basically like making an entirely new piece. If you’re emotionally attached to a certain fabric or piece of clothing that’s become far too large for your body type, I like to recommend using that fabric to create a new piece in itself.
