Madam Tilley is the lady who appears to be in charge of Le Soud's dress shop. She directs Belinda's fitting and also chooses which dresses Yvonne should bring to Belinda to try on. It is to Madam Tilley whom Mrs. Stafford-Smyth addresses the note instructing what kind of dresses she wants purchased. It is also Madame Tilley who tells Belinda that the cost of her dress has been taken care of and that the dress she wants will be delivered to her.
