VTG 60’s 70’s MCM 2 XS Dress Mod British GoGo Twiggy Orange Green Flowers Pink

This vintage, groovy A-line, knee length dress is by Mortimer’s from England. I couldn’t find much about this dress online, except it was designed in the UK in the 1960’s. This dress has a pocket, is belted, has pleats, and a hidden back zipper. The dress is in delightful shape. The fabric feels as if it has never been worn or maybe just once. It’s still stiff. There is light discoloration in the green in several spots. On top of the shoulders, probably from hanging up. On the bodice, close to the pit. I did rub it gently with a damp cloth, and it didn’t come off. But, that’s all I did for spot cleaning.
The fabric is a little dense with no stretch to it. It is ribbed, and almost has a sheen to it. And it’s an even happier color than what I am seeing on my screen!
Sour Apple Green, Barbie Pink, Indigo Purple, Pine Green, and Vivid Orange.
