Definitions

  • This invention relates to a supportive garment article, and a method of forming said supportive garment article.
  • the supportive garment article is suitable for use with an existing garment, such as an add-on to the existing garment.
  • Supportive garments are garments that are typically worn over the whole or parts of a body to provide support and comfort to the relevant parts of the body. Such supportive garments may be used for specific needs as required by the users. For example, garments like brassieres and compression tights may be used to improve the physical performance and/or appearance of the user, while garments like knee guards and orthopaedic supports may be used for improving medical conditions. Other examples of supportive garments include sleepwear, loungewear, sportswear and pants.
  • While supportive garments may provide the necessary support, there may be times when the support provided by such garments is insufficient to the user.
  • brassieres which are worn by most women on a daily basis, are able to provide the necessary comfort, support and modesty to women.
  • Flowever when working out or during sports activities, there is often a need for more support to the body part(s) in question. This is usually overcome by changing to other garments (e.g. sports brassieres) or wearing additional garments to achieve greater support.
  • sporting garments only provide overall support to the body part(s) and the amount of support at specific areas cannot be customised according to the level of activity and the individual’s needs.
  • such garments are usually thick and have wide, extended panels or paddings, which may be cumbersome to wear and may not be comfortable to the user.

  • the composite structure comprises the elastomeric portion and the fabric portion that are pre-bonded together.
