Dd is 6 and has always loved the beautiful frothy dresses in shops designed as bridesmaid dresses. We are going to a family wedding in a few weeks and I spotted a beautiful dress from john Lewis in a charity shop for £10. Very similar currently selling for £60. I bought her a cheap pink bollero cardigan to wear over the top. It is cream with a bow at the back. Now worried that I will offend the bride as I guess it was designed as a bridesmaid dress but I just thought it would be a chance for dd to wear a proper princess type dress.. I don't even know who she has as bridesmaids as I don't know her very well and would never have expected her to ask dd. Should I let dd wear the dress?
