More often than not, the solution involves swapping out my shoes or adding a few key accessories. Still, I've definitely gone overboard at times, adding one too many extras, causing me to wonder: is there a trick that ensures you'll always find that happy medium? Looking at street style images, I discovered there was, indeed, a popular yet subtle fashion formula, which I've since named the 'Plus-3 Rule.' Unlike other hacks out there that count the exact number of pieces to add to your look, this one focuses only on the statement-making additions (accessories, shoes, and layers) that take your outfit to a whole new level. 4 Accessory Tricks That Will Instantly Transform All Your Summer Outfits For example, let's say you're wearing a basic black dress and simple black slides. Alone, that combo might seem unexciting. However, with the Plus-3 Rule, you could add a shiny pendant necklace, a belt, and a floppy hat — three pieces that would all be eye-catching on their own. Alternatively, you might trade out your slides, which otherwise blend in with your outfit, and wear red heels instead. In place of the belt and hat, a fuzzy cardigan and a silk scarf would have a similar, fashion-forward effect. The way I describe the method in my head is 'Bam, bam, bam,' noting the three pieces that my eyes gravitate to first. But, it's best to explain it through photos. Ahead, take a look at some outfits that incorporate the Plus-3 Rule.

Black boots would have been the more predictable route, but instead, this street-style savant opted for a metallic pair, providing that third and final statement. With this rule, I also ignore the pieces that don't necessarily make or break the outfit. So, even though the bag and glasses are a nice touch, without them, it would still be just as fun.

It's the three accessories that really turn it into something playful and modern. 12 Ways to Wear a Bandana Earrings + Scarf + Colorful Bag Raimonda Kulikauskiene/Getty Images Normally, I wouldn't include a bag in this rule — it's possible you won't be carrying it all day long, after all — but the green design does lend a fun splash of color. Meanwhile, the scarf worn as a belt creates a unique twist. The third 'bam' in this case are the earrings, which add the final, dainty touch. Beret + Chain Necklace + Blue Platforms Christian Vierig/Getty Images Despite the fact that this outfit includes more than three accessories, these are the pieces that immediately command your attention and pack a punch. Plus, the blue shoes make it all the more special.

Orange Jacket + Necklace + Blue Slides Christian Vierig/Getty Images It's the colorful and shiny pieces that really wowed this time around, spicing up the basic t-shirt and skirt combo. Blazer + Pendant Necklace + Chunky Sandals Christian Vierig/Getty Images Although these glasses really pop, once they come off indoors, the key pieces of this ensemble will be the necklace, the shoes, and the light pink blazer.

Plus, without the large earrings and the vest, the outfit would be rather simple.

The hat, of course, stands out, and the Y-necklace provides a nice contrast against the white shirt. The final detail is the ankle socks, which quickly change up the look and give it a modern spin.
