Retro style strapless dress

Adorable retro design strapless dress . Brand is Twenty One . It is a size small . I have owned this dress for 20 years . No flaws in elastic , colors are still as vibrant as the day I bought it . There are a few spots on inner back of dress at the bottom ( as shown in picture) but is not at all noticable . My top half just doesn't fit where they should anymore , and must find it a new home .
