is it a blazer or a sweater?

my sis gave me this awesome sweater blazer thing i wore today and i am completely IN LOVE with it. it's warm, comfy and just so cool.

outfit details: dress - f21, sweater blazer thing - my sis 

my allergies must be kinda weird because i have been living in a fog for a week. hence, why i look so funny. lol.

and one more pic for fun of me with the puppy. it's been a minute since i've posted a pic of her!
