IS THE SUIT TOO BIG?
You should be able to gauge if your son's suit is too small if the blazer sags or bites around the shoulder area, and when buttoned, flares outwards, or less than 80% of the buttocks are covered. If his trousers feel too tight when he makes normal everyday movements, this could also be a sign that the suit is too small.
If you're worried your son's suit may be too big. you should be able to notice this relatively easily from how it sits on his body. Some evident signs include the shoulder cushions surpassing where his shoulder ends, the jacket looking and feeling uncomfortably loose, and the trousers hanging below the ankles and draping over the shoes.
