Size 4, but run small. Honestly I believe these could fit anywhere in the range of size 0-4, but in my opinion would probably fit a size 2 best. That’s why I’ve simply listed them as size “small”….but could also fit extra-small. Measurements pictured to ensure fit. Keep in mind that the waist has a good amount of stretch.
