Choose a blazer to dress up your denim shirt. Pair a denim shirt with a maxi-dress for a bohemian vibe. Add a vest to your ensemble for a preppy touch."
This works well with baggy sweaters as well as more fitted ones. For the best look, wear a denim shirt with longer sleeves so you can roll the bottoms up over the cuffs of the sweater. Make sure to pull the collar out so it’s visible over the sweater.  Cardigans work well for this look, too. If you’re worried about looking or feeling bulky because of the multiple layers, try tucking the denim shirt into your pants. This will help hold the shirt down so it doesn’t bunch up under the sweater. This is a great way to dress down an outfit or show off a cool shirt. Stripes look great with denim, but don’t be afraid to wear a graphic tee or something bright and patterned. Stick with neutral tones if you want to maintain a classic look.  This essentially turns your denim shirt into a cardigan or jacket. If the weather is cool, you could even wear a long sleeved shirt under the denim one and roll the bottom cuff up over the denim cuff. This creates a nice visual effect between the 2 shirts. This is a really popular style for both men and women to wear to the office. You can button the blazer to make it look a little more fitted, or leave it unbuttoned to show off your layers even more. Make sure to pair your blazer with bottoms that complement the entire outfit. For example, you could wear a navy blue blazer, a light-denim shirt, and a pair of khakis for a neutral yet classy style. Try just tying together the bottom of the shirt rather than buttoning it up, that way the top of the dress will still be visible. If you get warm, you can take off the top and tie it around your waist.  This is a great way to transition your maxi-dresses from summer to fall. You have an extra layer in case you get cold, and it lets you enjoy those dresses for a few extra weeks before it gets too cold to wear them. You could even wear a maxi-shirt and a tank top and put the denim shirt on over the tank top for a very similar effect. If the temperature is cool, don a puffy vest overtop of your denim shirt the next time you head out. Leave your denim shirt buttoned, but leave the vest unfastened. You could even add a scarf to the outfit for additional warmth. Pair the vest and denim shirt with black jeans or leggings to really pull the look together.
