Long-sleeved, short-sleeved or no sleeves at all, an oversized button-down is a major closet must-have. Its versatility proves itself season after season, and this summer is no different. From a fabulous finishing touch to a ’70s-inspired getup to a lightweight dress that’s perfect for all your off-duty outings, the options are endless. The best part about this timeless topper? Your brother, boyfriend, dad or BFF no doubt has one kicking around, meaning no purchase necessary.


1. @emmahill: Take your off-duty style on a trip down memory lane by pairing up this season’s hottest skirt silhouette with a button-down topper in a relaxed fit. To complete the ’70s-inspired ensemble, go with classic aviator shades and a pair of gladiator or chunky sandals. (via @emmahill)


2. @hannahakinyemi: Balance out borrowed-from-the-boys separates with subtle sultry touches that add an instant feminine edge, like a bold red lip and unexpected styling. (via @hannahakinyemi)


3. @carolineeetanujaya: Layering a short-sleeved chambray top over a colorful casual dress is perfect for infusing your weekend duds with a little ’90s flair. Extra bonus points for adding on a bowler hat and on-trend round sunnies. (via @carolineeetanujaya)


4. @modernensemble: When you’re not feelin’ that whole pants thing (and most of us aren’t when the temperatures start to climb), simply throw on an oversized number and go. A few funky accessories and a stylish cincher will keep the look feeling put-together and polished. (via @modernensemble)


5. @mija_mija: Boyfriend jeans and a relaxed fit shirt are always a winning pair. How we like to wear it? With killer pumps and a crazy stylish clutch, of course. (via @mija_mija)


6. @remiafolabi: Instead of whipping out your go-to warm-weather topper, why not try a menswear shirt instead? The lightweight material is ideal for when things start to heat up and rollable sleeves mean you can easily adjust to changing temps. (via @remiafolabi)


7. @ezzentrictwee: Go oversized to give sassy skirts and shorts a laid-back, effortlessly cool edge. High-top kicks are a must. (via @ezzentrictwee)
