What Detail Is Needed
The size tag is a label or another indication (printing, stamp) of the size of the item.
Please refer to examples below.
Where to Find It
In sneakers, size tags usually are labels that are found inside the shoe.
In other types of shoes, the size might be a print stamp on the tongue of the shoe, often found together with the model code. This is typical for luxury brand shoes (~ heels).
In clothes, it is usually a small label that's found around the collar label, the care label or in another inner area of the piece.
What We Want to See
This photo is needed for us to clearly inspect the fonts and the overall look of the label or indication.
How to Take a Good Photo
Make sure that the label is flattened and the whole surface is clearly visible. Please always upload high-resolution photos.
