To ensure that each item you receive fits right, we have provided a sizing chart on each product page. Due to the nature of our print on demand service, we cannot refund or exchange items that do not fit. These sizing charts are specific to the different fit of each shirt. Each shirt has a length and width measurement.
Length: This is measured from the collar to the bottom of the shirt.
Width: To measure the width of the tank top, measure around the fullest part of the chest 1" below bottom of armhole seam.
The diagram below is showing how to measure the width.
