Thank you for viewing. This is a 4°C dress. It's made of a light suede-like material, with lace detailing on the chest, hem, and sleeves, giving it a very elegant feel. Paired with accessories, it would be suitable for parties and formal occasions, and you could also wear it to the office with a jacket or cardigan. The armpits are open, so you shouldn't have to worry about sweat. It would also look lovely with a turtleneck sweater underneath. It's a little small on me, but it's a beautiful dress, so I hope someone who fits it will wear it. ● Condition: The tag has been removed after purchase, but it has only been tried on at home, so I've marked it as "Like new." ● Size: 36 (Equivalent to S) ● Color: Dark Navy Color...Navy Pattern/Design...Solid Sleeve Length...Short Sleeve Season...Spring, Autumn, Winter Please feel free to ask any questions in the comments.
