Hi my daughter is going to a "graduation" ball from college in two weeks time. Due to Covid she missed out on all her previous leaving dos/balls etc and she's not going to uni so we really want to make it work for her. She's had a number of mental health issues and because of this there are some specific requirements for a dress i.e long sleeves (to cover her self harm scars). She's also tiny, 5'3 and very petite, and flat chested, so nothing too plunging or ridiculously long. She doesn't like sequins or frills (this is a girl who is most comfortable in riding boots and jodpurs). She likes black, dark green, or strong colours, not pastels. Budget wise we can only go up to about £80 - 100. Can anybody help?? We'd be open to hiring or buying. Thanks so much!!
