This is a one-size-fit-all high collar tank top, and it falls above the belly button. It has great elasticity to fits perfectly and comfortably on most body type, but if it is overstretched, you may see through it, so we suggest that your band size should not be over 40\". The mock collar is double layered and it is designed to flatter your neck lines and make your neck longer visually. On the surface of the sleeveless shirt, there are jacquard corduroy-like stripes, but it is plain inside so that you won\'t feel any friction. To avoid splitting, we have edged it with elastic fabrics of the same color.
