Blue and Yellow striped baby top size M

Brand is not something I’ve heard of, but I think I bought this at a discount store like Marshall’s or tj max years ago, and I have never worn it. It has been washed. I hate showing off my upper arms and the sleeves are short. The material is buttery but I cannot read the washing instructions/material tag anymore. Measurements laying flat: Shoulders: 14.75” Pit-to-pit: 16.75” Sleeve: 6.25” Front Length: 18.5”
