Here are a few things to imagine when the sweater is too big. Shoulders – when the seams are way past where the shoulders start to slope down, this is big already. Another thing to note is when the seams just rest on the upper parts of the arms. This size is too big. One should go with a smaller size. Neck or Collar – one can tell when the sweater is too large by looking at the neck or collar. When one can see the sides of the collar, this is too big. Also, try pulling the sweater forward. Aim for the V to rest against the shirt collar. If the V goes way past the top of the armpits, this is a bigger size and should not be an option. Sleeves – the sleeves should end at the end of the wrist. When it goes beyond that part, the size is too big. One thing to also note is when the sleeves are too big and baggy. This should look floppy as well. Body Length – if the sweater goes about 2 inches below the belt buckle, this is too big of size already.
