Tommy Hilfiger Pleated Chambray Dress Blue 10

Tommy Hilfiger Pleated Chambray Crocheted-Hem Dress. indigo, Tommy Hilfiger, blue chambray dress, sleeveless pleated dress, no sleeve dress, and blue pleated dress. Size 10. Wishful thinking I bought this dress for myself but it doesn't fit. I do believe it fits smaller than a 10. This mannequin is usually a 10 and I can't zip it. I believe it's closer to an 8.
