Zara is not HRH. Beatrice & Eugenie will have need of tiaras when attending state banquets etc. Given the fact that her father is not married at present it has been suggested that Beatrice will become her father's partner @ such functions now that she is 18. Once she finishes school she will be taking up duties. There is going to be some shortage of royals to cover duties in the next few years. The Duchess of Kent has retired, Princess Alexandra turns 70 at Christmas. With the deaths of Pncss Margaret & the Queen Mum and Andrew's lack of a wife there is a dearth of royal ladies to perform the expected duties. At present there is only Camilla, Sophie, Anne, the Duchess of Gloucester & Princess Michael. In that group Camilla turns 60 next year, the DoGlstr is nearly 61, Anne is 56 and, I think, Princess Michael is a similar age. That only leaves Sophie in the under 45 bracket & it is not inconceivable that she may have another child. Beatrice & Eugenie are going to have to take up some of the slack at least until William & Harry acquire wives.
