CrocsWomen 208180-001 Classic Platform Slide

Some reviews that say to size up and others to size down. Can anyone who bought the women’s size 6 or 7 say what the heel to toe length is? Thanks

Are the moon jelly ones blue or lavender?

Had to order a size down but they are a bit narrow. Will they stretch over time?

If I size up will the shoe be a little wider on my foot?
