Luella denim jacket size Large

Adorable denim jacket by Luella. I fell in love with the yellow accents and zippers and the entire vibe of this jacket but unfortunately it’s just too small for me. The tag says size Large, but honestly this really fits more like a small. It’s very snug in the arms and shoulders for me, so I’d say this would best fit a size 4-6 ideally. No flaws that I can see, just a fun little jacket with so much character. Please inspect photos and video for all details on condition etc. Measurements are: pit to pit 15” shoulder to shoulder 16” waist 15” and length from top of shoulder to bottom hem is 20”. Any questions, please ask! Thanks!
