Vintage Sweater Dress Set

I’m obsessed with this vintage sweater dress set but I don’t have anywhere to wear it. The dress is mid length (40 inches long), light sweater material (has some stretch), and zips up in the back. The sweater is the same material and ties in the front. My only complaint is the lack of pockets. I’m guess it’s a size small. I’m 5’6 and 130lb for reference. I usually wear a size 4 or 6. Please let me know if you have any questions!
