White polka dot mini dress with back ties and matching slip

White polka dot mini dress with cute back ties. Dress is two parts - transparent overlay with a shorter, simple white slip underneath. The parts could also be worn separately! Only worn once to my rehearsal dinner and is in ‘like new’ condition. Dress is very comfortable and easy to wear. Size is XS but fits on the loose side so could fit someone who typically wears a size XS/S. For picture reference I am 5’9”.
