I need a general fashion advice, please help
Hi, 18 year old student here. I always like to dress well, but unfortunately i dont know the essentials. I will attend university in autumn and i need some advice on how to dress up good. I like to dress business casual, especially the combinations where I can wear a sweater over a shirt and tie, but I don't know what kind of pants to wear under it. Also, I don't know much about colour palette, I always preferred colors such as navy, blue, black for shirts and green for sweaters. Due to my body (I'm big lol), I also cant find good pants to wear. In general, I need a big fashion advice.
