There were several types of women's foundation garments in the 1920s. The foundation garment served to retain the correct lines in a garment. Which foundation garment was worn depended largely on the specific lines of the garment and the material of which it was made.
The foundation garments were grouped into two general classes: waistline foundations and lining foundations.
Waistline foundations consisted of two types:
- Inside stay belts
- Fitted hip yokes
- Camisole or bodice lining
- Built-up or plain-waist lining
- Close-fitting lining
- Foundation slips
