I bought this top in my usual size large based on other reviews and it fit perfectly.   i have long arms and the sleeves are the perfect length.  the fabric is a slightly stretchy jacquard and very nice quality.   the top is definitely more fitted with a significant amount of fabric at the peplum portion.   i wish that this was a bit less, which is why i only gave it 4 stars.  otherwise, it's a great top for fall that can be dressed up with a pencil skit or more casually with jeans.  definitely
