502 Biologia Advance slim-leg jeans from Levi's. Crafted from a durable cotton denim with a little elastane for stretch and to keep their shape, these Levi's 502 jeans are a contemporary update to the classic 501 style with a slimmer leg that tapers slightly at the ankle. Featuring five pockets, a traditional button fly, and a subtly worn-in finish, this slim style is comfortable enough for everyday wear and smart enough for work or nights out. Other colours also available. Colour: blue
