Size 4?! I'm around your height and in Germany I'm a size 40-42. So Bust is 35-38 inches. Waist ranges 28-31. Hips range 38-40 inches. Back when conversion meant something a US size 4 would be a german 34. Ranges are: Bust: 30-31 Waist: 24-25 Hips: 33-35  I would be in shock if I could fit in something described as 4 sizes TOO SMALL.
