Plus Size Denim Floral Print Midi Dress, High Neck Mesh Sleeve Belted A-Line Dress with Front Slit & Pockets

Bought this dress for a denim themed office party however it is not denim it is a blue polyester material. The belt looks nothing like in the picture. The dress looks similar but it isn't the dress in the picture. The upper part of the sleeves are too tight can't even raise my arms. The rest of the sleeve is way too big. It's too late for me to get another dress so I'm going to try to see if I can find a seamstress to fix the sleeves. The flowers on the bottom are dull in color. I'm 5'2”, 211lbs, 46/38/49 measurements normally wear a 14/16 dress or XL night this dress in a 3X fits everywhere except the sleeve issue.

It is not Denim and the print is not dark like denim
