Answer:
An outfit does not fit the model properly
Step-by-step explanation:
If an outfit does not fit the model properly, then the measurements would've been inaccurate. Otherwise, the outfit would've fit the model.
Deciding to use fabrics of higher quality does not have anything to do with the measurements of the model.
If a dress or a suit drapes and flares exactly as expected, then it has been measured and made correctly.
If you need to buy more fabric, it would be a consequence of incorrect measuring, but needing to buy less fabric wouldn't.
