L.L.Bean Denim Long Sleeve Button down Collarless Dress/Light Denim Coat

Bought this from a vintage seller on Etsy, it's a gorgeous LL Bean find! I don't wear it as much because I prefer to have gathers on the waist and this one is a clean, straight cut. I wish I had the body to carry this off, but alas! Hoping someone who loves it gets to wear it :) Size tag says 16 Tall, but it fits like an L or XL at the most. Measurements - Length : 54" Armpit to armpit: 21" Shoulder : 16 1/2" Shoulder to end of Sleeve: 25" Waist : 38" Hips : Free Condition : Gently used. There's no stains or holes. Great condition with tons of wear left!
