WEDDING bells are ringing tills at a Barnstaple charity shop after a mystery donor dropped off a stunning haul of beautiful wedding dresses for staff to sell.A corner of the Cancer Research shop in Gammon Walk has now been transformed by a riot of white taffeta, lace, satin and silk, thanks to the generous donation of 20 apparently brand new dresses worth up to \u00A3700 each.Stunned volunteers at the shop told how a woman left the box of dresses without leaving her name."A lady stopped by one day last week and said she had a number of wedding dresses we could have," shop volunteer Barry Kissack told the Gazette."The following day, she turned up with a box of them. People drop things off here all the time and we didn't ask her name. We'd like to say a massive thank-you for such an amazing donation."Mr Kissack's wife, shop manager Dorothy, said that the dresses - from sizes 10 to 16 and being sold by the shop from around \u00A3250 - had never been worn and many still had their original price tags attached.She said: "We were very surprised and excited to be given a collection of such new and modern dresses."People have donated individual dresses in the past, but we have never been given anything like this before."Wedding dresses are so expensive and as we are coming up to the wedding season, I hope brides-to-be will be able to find their perfect dress here and help the charity."We displayed a pair of dresses in the shop window a couple of days ago and some have already been tried on by girls getting married this summer." On Friday, five girls from North Devon College's learning support group - many of whom volunteer their time to work in the shop - agreed to model some of the dresses for an impromptu photo shoot outside the shop.It provided the girls with the perfect opportunity to practise their catwalk skills ahead of a Cancer Research charity fashion show at the Cedars Inn on Wednesday, June 18.
