Steven Alan Padded Vest

I bought this last winter, but the size doesn't fit, so I'm selling it. The retail price was 33,000 yen.
It's new. The following is a reprint of the product description:

---------------------------------------------
Lightweight and warm reversible vest with padding.
The outer fabric uses "Pertex Quantum," a material with windproof and water-repellent functions, and the padding uses Thinsulate, a high-performance padding material that is lightweight, warm, and has a soft texture.
The thin padding and supple fabric make it non-bulky, lightweight, and comfortable to wear.
It has a moderately relaxed silhouette that is easy to wear as an outer or inner layer.
The streamlined look without bulk is also a key feature.
It can be worn reversibly, and the pockets on the reverse side have concealed zippers, designed to be as simple as the front.
The stitching on the reverse side provides a nice accent, allowing you to enjoy a different look on the front and back.
It's easy to adjust the temperature with layering, and it can be worn for a long season, as an inner layer in winter or as an outer layer in early spring.
