Make sure your V part wig fits your head before wearing it if you intend to wear it with glasses. Measure your head size properly before purchasing a wig. To acquire reliable results, you’ll need to take many measurements. If your wig is excessively big, it will not fit properly on your head, and the ear tabs will fall too low, interfering with your spectacles.
