Seeing the humongous black hat of the gentleman in blue gown, I instantly thought of Mr Arnolfini. Also, the pattens here are of the same design as in the Eyck double portrait. The women wear houppelandes with overturned collars and horned headdresses, supported by padded rolls. The gentleman accompanying the blue lady also wears a padded headdress, and a red scalloped tabards over, presumably, short gown with bag sleeves.
Two interesting points here: Firstly, note the looseness of the blue sleeves of the pink lady’s underdress, and the size of her houppelande’s sleeves (the dress looks almost a cloak, really). Secondly, the houppelandes have a gold line under the overturned collars, reminiscent of the fur edging of the Margherita’s version of the houppelande (which lacks the collar). I think these are some kind of either necklaces or - what I find more likely - applied embellishments.

Woman on the far right is wearing a puce houppelande with downturned contrasting collar; her sleeves are cuffed and her hem is edged in white. The sleeves are still baggy, but the style of the houppelande is all in all much less voluminous at this stage, on its way to evolve into the full-fledged v-neck “Burgundian” gown.
