Wedding season is fast upon us, but with the average cost of the big day hitting £25,000, thrifty brides are on the hunt for ways to budget. It's easy to cut costs by snapping up invites and decorations on the high street, but would you buy your wedding dress from the likes of Monsoon or Debenhams? Or would you rather make like the A-list and splash the cash on a timeless Vera Wang or Oleg Cassini gown? As millions of brides begin the hunt for their perfect dress, FEMAIL has pitted the best dresses on the high street against the more high-end gowns. So, can you tell which gowns cost hundreds and which sets you back thousands? BRIDES . DEBENHAMS VS WHITE BY VERA WANG . Debenhams is one of the most popular dress vendors on the high street and the store has added a covetable bridal collection to its repertoire. Describing the wedding range on its website, Debenhams say the classic and modern styles are designed to make you 'look and feel fabulous' on your big day. On Debenhams.com, one £199 dress  is described as a 'beautiful Grecian inspired gown crafted from satin with beautiful chiffon straps and waterfall detail to the centre front and back.'
