Vintage Barbie Cloud 9 #1489 (1969 - 1970)

Blue Satin Robe with Hot Pink Shawl Collar
Blue Peignoir with Hot Pink Top and Blue Panties
Hot Pink Slippers with Blue Ruffle

In this picture the hot pink looks more orange - it is a true hot pink and is much prettier than it is represented here.

This is one of the harder to find nightgowns for Barbie. 

The robe and gown are both blue satin with sheer blue nylon over it. 

The robe is long blue satin with the hot pink collar and a blue satin bow.  The short nightgown has matching panties.  The hot pink satin booties - which are very had to find - are trimmed with a sheer blue ruffle.
