We have a family wedding coming up in a few weeks and both my dds have had dresses brought for them to wear by the bride. My 12yo is very tall and the biggest size dress (age 13-14) is coming up to mid thigh. The options appear to be get a dress maker to add a panel at the bottom of the dress to give it length or wear something underneath it.
Any suggestions as to what could be worn underneath so it doesn't look naff?
