Jeans & a cute top is my go to fall outfit. Jeans are Free People barrel jeans - a bit pricey but truly my favorite jeans from last season that I wear all the time. Top is Amazon and under $30. Has a cute little off the shoulder detail! Bag is Amazon keeps going in and out of stock so I linked some similar :)
Sizing:
Jeans - run really big, I ordered two sizes down (wearing a 27)
Top - true to size, M
