Solid Color 3/4 Sleeve Stripe Day Dress

I bought this dress from TB Dress and it does not fit me at all. It is a size XL, but really looks like a MEDIUM. I can't give more accurate information since I can't try it on since it doesn't fit. It's a really cute casual dress, but is not true to size measurements. MEASUREMENTS: LENGTH: 86, BUST: 98, WAIST: 86, SHOULDERS: 36 SLEEVE: 46
