DD is going to a uni open day next week and it is supposed to be very warm- 28 degrees!! She was going to just wear jeans and a nice-ish top with some comfy trainers but now she is faceing a bit of a dilemma as it’s going to be so hot. She ownes a few casual summer dresses and shorts but as she is quite tall they all come up quite short on her. We’ve not been to a uni open day before and are not sure if this would be viewed as acceptable attire, so any thoughts or suggestions would be much appreciated! TIA
