Kelly's prom dream comes true thanks to free online dress service

For many students the end of exams or school has been marked in the last few weeks by a prom.

But Kelly, like many teenagers, may have missed her big night, or gone into debt, because of the expense of buying a ball gown.

The 16-year-old has recently been treated for Hodgkin lymphoma, an uncommon cancer, and was able to borrow a dress for free.

Kate Lambert, from Andover in Hampshire, has spent the past few months collecting donated prom dresses and setting up an online service to lend them out.
