These are two sizes of bottoms from Agent Provocateur, Mazzy style, light pink on black. Size 3 or size 4. I am a 27" waist with 37" hip and size 4 bottoms fit me better than size 3. The size 4 is worn 3 or 4 times only, size 3 I tried on but never actually wore. I loved this bathing suit but have aged out of it. Its in good condition. Size 4 pictured. Top is size 3 and listed separately (top listing: https://poshmark.com/listing/Agent-Provocateur-Swim-Mazzy-Top-Size-3-64a8a1668fa207083ee8f367).
