ASOS Denim Dress with Snap Buttons UK Size 4

I’m a US size 2 and this dress fit me really well, just bought a new dress that looks too similar. In dresses I usually sit between a XS and a S. I would say this is more of an extra small than a small because there isn’t any stretch to it. *Please bear in mind this is a UK size 4, not US. The US size is not listed.* Similar in style to #topshop #Y2K #2000s #vintage #jean
