If you're starting to build up your spring and summer wardrobe, a trip to Kohl's is a must. The LC Lauren Conrad collection has lots of warm-weather essentials, like the perfect denim shirt, denim vest, denim jacket and white skinny jeans. If you follow my daily "Dress by Number" posts, you'll see these pieces come up again and again because they're so versatile and work with almost any style aesthetic, whether you're bohemian like Alessandra Ambrosio (seen in a white jean jacket here), chic like Miranda Kerr (seen wearing a denim shirt here) or trendy like Jessica Alba (seen wearing a denim vest here). But instead of paying hundreds of dollars for designer takes on these pieces, you can find them for under $30 or $40 at Kohl's. Sometimes less. Other highlights included cute day dresses, pretty blouses and breezy skirts. See more of my real-life photos after the jump (I couldn't resist mixing in a few items from other in-store brands, too, so let me know if you have questions about any of the items).
