I bumped into a little shop in Etsy today, it's called FlowerZero
They have the most lovely shoes for SD girls, such as these 1940s styled pumps with laces
They are absolutely adorable and the price isn't bad either. A bargain I would say.
For MSD girls they have lovely early 20th century boots in both black and brown. They would look great with either belle epoque or 'Little House on the Prairie' style clothing.
They also have some sweet wigs such as this purple wig and also some outfits and doll instruments.
