    Arrival time
    Size: 8, Color: Black Wc
    Disappointed I ordered them thinking they would arrive when they said they would and they did not! Ordered two pairs and run extremely big!

    Returned
    Size: 8, Color: Spiced Nutmeg Cs Wc
    The suede and color were great but the boot didn’t fit. The calf fit was way too big and the toe was so pointy it felt and looked weird to me - made my foot feel cramped and looked like I was wearing two sizes bigger. The heel was nice though.

    A beautiful dress
    Size: Medium, Color: Red Rose Floral
    Why did you pick this product vs others?: I absolutely love this dress. It is the first item of clothing I have purchased from Amazon that I haven't had to send back. The sizing is spot on. This dress is indeed 100% linen. The workmanship is great. It is truly a beautiful dress and it brought me many compliments.
