This is a fabulous orange and black silk maxi dress by Bara Fashions of London from the late 1960s early 1970s.  The dress is in a beautiful stylised floral print in shades of orange and black,  has a wide neck,  long tapering sleeves with puffy shoulders and the bodice is shaped by the use of lots of seams back and front which gives a very flattering fit.  The over dress flares out from the seams and finishes at mid calf and the underdress has a deep frill - sleeves and both dress layers are finished with rows of black braid.  The dress is fully lined, has a long back zip with a hook and eye at top and fastens with velcro at the cuffs (not sure if this is original!). There is no size label in this dress but it is shown on my size 12 mannequin which it is loose on - measurements are as follows :  Pit to Pit 56cm (22") approx / Shoulder to Shoulder 41cm (16") approx / Sleeve Length - shoulder to end 58.5cm (23") approx / Waist - side seam to side seam 43.5cm (17") approx / Hip - side seam to side seam on the lining dress 51cm (20") approx / Length - nape to hem 145cm (57") approx.  Please note this is a stunning true vintage dress and has been worn but is in very good condition - I bought this a long time ago but have never had the right occasion to wear it - so am now moving it on.
