3 Terms and definitions
For the purpose of this document, the following terms and definitions apply.
3.1
knitted shape underwear - figured-style
Underwear that pulls or constrains specific parts of the human body to maintain or
adjust the shape of specific parts of the human body.
4 Product classification
According to the function, it can be divided into reshaping knitted shape underwear and
light-shaping knitted shape underwear. Reshaping knitted shape underwear generally
has supporting parts and its traction or restraint effect is relatively strong; light-shaping
knitted shape underwear is generally made of high elastic fabric and its traction or
restraint effect is relatively weak.
5 Product size
The size is indicated by the cup code, the chest circumference (underbust grith) suitable
for the human body, the waist circumference, and the height (in centimeters). The
definition of the cup code and underbust grith shall be implemented in accordance with
the provisions of FZ/T 73012.The specific provisions are as follows.
a) Shaping brassiere (Figure 3). mark the cup code and underbust grith.
Example.
B75, indicating a B-type cup, and underbust grith of 75 cm.
b) One-piece shaping garment with cups (Figure 4)/one-piece shaping dress with
cups (Figure 5). mark the height, cup code, underbust grith, and waist
circumference in sequence, and the height is separated from the cup code and
waist circumference by “/”.
Example.
160/B75/64, indicating a height of 160 cm, B-type cup, underbust grith of 75 cm and waist
circumference of 64 cm.
c) Shaping panty (Figure 6)/waist cincher (Figure 7)/short shaping skirt (Figure 8).
mark the waist circumference.
Example.
64, indicating a waist circumference of 64 cm.
d) Back-supporting garment/shaping garment (Figure 9). mark the waist
circumference.
Example.
64, indicating a waist circumference of 64 cm.
e) One-piece back-supporting garment/one-piece shaping garment (Figure 10)/one-
piece shaping dress (Figure 11). mark the height, chest circumference and waist
circumference, with “/” separating height, chest circumference and waist
circumference.
Example.
160/75/64, indicating a height of 160 cm, chest circumference of 75 cm and waist circumference
of 64 cm.
