Going to work during the holiday season sometimes makes you confused about what to wear. Look at the collection of your clothes in the wardrobe for a moment to find the proper outfit. I understand that it will take your time. Just try to combine and match the jeans you have with a simple top to make you look casual.
If you wear jeans with sweaters or shirts, add something to light you up. Such as accessories, scarves, nice handbag, etc. Otherwise, if you wear a dress, combines it with sneakers for a casual impression. Then, sunglasses will also be significant for your holiday work outfit.
