EUC Torrid Swimdress Size 5, fits like a 4 Black with stars

This is a beautiful and flattering swimdress with a full brief underneath, bow detail in the front, and flutter sleeves. I word this maybe twice - I’ve lost weight and it doesn’t fit me anymore. I always size up in Torrid swimwear/ this is a 5 but fits like a 4. Black with white stars.
