There is no size marked on the garment.
These combinations are unworn, and in good condition.
They are unsold shop stock from the early 20th century.
They have been properly stored in the shop, for about 100 years, and are free from major damage, but they have discoloured over time.
There are storage marks along the fold lines, as you can see from the photographs.
I have not attempted to clean the garment, as I think this is probably a specialist job best left to the experts.
In view of its age, this garment must be carefully stored, away from clothes moths, and treated gently.
