I typically wear a 5.5 in shoes but I ordered a 5.5 in green and a 6 in leopard -against the advise of other reviewers. The 6 actually fit the best with a little toe wiggle room but the 5.5 isn't too bad and def still wearable. Both shoes look cute on and the green is very vibrant. One star off because, duh, the material and sole are not great quality. But I wear all black for work and enjoy a pop of color from my shoes and for 9$ this is perfect to wear and then ditch.
