This one is the real deal, and it's a bit unusual.  Most Vested Gentress pieces are screen printed on a white cotton/poly poplin, though you also see the same fabric in pink, yellow, green and aqua.  I got these photos from Sue Langley last week after she saw my previous post about the Vested Gentress Gingham Horse print.  Instead of the usual white or pastel, this is printed on a gauzy cotton gingham.

Sue also had a story to tell :

When I was a teenager, an elderly school principal friend of my mom's wore one - and that I'd lusted after it ever since. It seems to me that her's was a bit more late 50s though, with a dirndl skirt perhaps. I do vividly recall the bows on the horses' fannies and my mixture of shock and admiration that this lady would wear a dress like that. 

How I wish I'd taken a photo of the school principal in hers (it would have been 1958-60 I think); it seems to me that the horses' manes and tails were fine string, and the tails did have bows.

Now that's interesting, because Vested Gentress opened in 1961.  Could it be that the idea was not original to them??  The plot thickens!  Any way, enjoy Sue's cute new dress.
