The page is rendered with JavaScript making more requests to fetch additional data. You can fetch the complete page with selenium.
from bs4 import BeautifulSoup
from selenium import webdriver
driver = webdriver.Chrome()
url = "https://shop.nordstrom.com/c/womens-dresses-shop?origin=topnav&cm_sp=Top%20Navigation-_-Women-_-Dresses&offset=11&page=3&top=72"
driver.get(url)
soup = BeautifulSoup(driver.page_source, 'html.parser')
driver.quit()
print(soup.prettify())
