I’m 5’5 and I’m wearing a size UK6 in the sustainable white and blue mini dress. Size up if you are worried about the length. It’s stretchy abs you can adjust the strap. If you like me have a smaller chest, you won’t need a bra set. The dress is structured and gives support. My brown tribute sandals are true to size. My bag and hat are old, so I have linked some similar ones ❤️ #LTKDay
