Yellow silk spencer in the Charles I revival style worn by Margaret Maskelyne. The spencer is of yellow satin weave silk with an all over foliate style in a darker yellow thread. The spencer has a round collar edged with yellow pasmentarie. Under the collar are three triangular pendants imitating a Jacobean doublet, two fall in the front and one in the back. These are edged with yellow pasmentarie and each has an applied domed button of yellow silk floss over a wood core.
The tops of the sleeves are capped again imitating a Jacobean doublet. The caps are edged with yellow pasmentarie. The sleeves do not have cuffs but are edged with yellow pasmentarie. The spencer has a central front vent with 5 button fastenings. These flat buttons are covered in yellow tabby weave silk. They button into a silk plaque which is concealed so that the effect is of 6 silk floss buttons as fastenings. The 6 silk floss buttons are edged by a double row of yellow pasmentarie.
From the back it is apparent that the back of the sleeves have a full gather at the shoulder. At the bottom hem of said spencer is an applied yellow silk ribbon which is meant to tie in the front. Just above this are 2 domed silk buttons one on either side. The interior is fully lined with a finely woven cotton linen blend. At the bottom hem at the back is a cream silk ribbon to secure the fit.
