Slim Fit Long Sleeve Polo Dress

I ordered this dress in 2 sizes (my regular and one size bigger) since the material has no stretch. My usual size 4 is tight in the hips and chest. No big deal, I tried on the bigger size and unfortunately the dress is still a wee bit clingy for my taste. I would have kept the bigger size except for the abnormally long sleeves which extended way past my palms. I'm not sure if I should alter the sleeves since they are bell sleeves. But otherwise a great versatile dress that easily pairs with sneakers or heels.
