My sweater is from New York and Company (it’s called Long Sleeve Fair Isle Stripe Sweater in black and white) and I also linked similar options.
My jeans are from madewell last year and sold out in this wash. I linked this year’s washes in the same style (perfect vintage straight jean).
Stay true to size if you want a looser fit and go down one for a more true to size fit. The most comfortable jeans I’ve ever worn!
