This lovely blue floral gown is a vintage piece. The dress was made available in the 50s in three different colors – blue, pink and green.

The blue gown was featured in the 2007 first season of Mad Men on January Jones as Betty Draper. An interesting note about this dress, is that it was the gown that Mattel chose to use when creating a Betty Draper Barbie Doll.

The same blue vintage bubble dress was seen again in the 2019 third season of The Marvelous Mrs.Maisel, where it was worn by an extra, and most recently on an extra in the 2021 second season of Why Women Kill. 

With most costume dramas it is safe to say the dress reuses are exactly the same. However, when you start to get to pieces that can still be found in vintage shops, there is the possibility that more than one copy is floating around. Sometimes in shows if there are multiple overlaps, it’s safe to say it’s the same dress - for instance, Mad Men and The Marvelous Mrs.Maisel have another costume in common, which you can see here.

However, in this particular instance – while it’s the same model of dress most certainly, it is not the exact same dress, because I happen to own the dress worn by January Jones. The gowns seen in Maisel and Why Women Kill, however, could possibly be the same exact gown.
