Summer is here, and with it comes the desire to showcase a lot of skin! We reveal where fashion mistakes are lurking and how to easily avoid them.

1. Fashion Mistake: Transparent Bra Straps

This summer, asymmetrical tops and dresses are all the rage. No wonder, as these feminine pieces not only look stylish but also add a touch of romance to everyday life. The challenge with this outfit choice is clear: A bare shoulder calls for an invisible bra solution. But even when in a hurry–stay away from bras with transparent latex straps! The joy of feigned nudity is short-lived, as plastic straps make you sweat even more, and it becomes visible very quickly. It’s a myth that these fabric substitute straps are discreet and nearly invisible.

It’s better to choose a strapless option; thanks to a wider underbust band and an inner latex layer, good strapless bras don’t slip even with a larger bust. Those with a smaller bust can opt for bandeau bras without pads or simply go without a bra altogether.

2. Fashion Mistake: Wrong Underwear Under White

Speaking of underwear: Your outfit can be meticulously chosen–if the underwear doesn’t fit, the overall impression is quickly ruined. Especially nice in high temperatures: An all-white outfit that can even rival the classic blazer and suit pants combo. But beware when choosing your underwear! Even white jeans made of relatively thick fabric don’t forgive dark underwear and mercilessly reveal black panties. If you think white is the right choice under white, you’re mistaken: Bizarrely, underwear in this color has the same penetrating effect as dark shades.

Surprisingly, the color red provides a solution, becoming nearly invisible under white. Also, laser-cut hipsters in a tone similar to your skin color keep hidden what they don’t want to show–it may sound unsexy, but these panties also have the advantage of being somewhat shaping.

3. Plastic Flip-Flops

At first glance, flip-flops seem harmless, but these colorful plastic sandals have the power to ruin an entire outfit and reveal themselves as a fashion mistake! Especially in the office: When in doubt, there’s always a shoe that’s nicer than a flip-flop! In professional life, they mainly express one thing: carelessness. However, if you must have a thong sandal, opt for a leather model–they’re quite trendy this year. Made from high-quality material and with fashionable details like feathers or braiding, these sandals are more like sandals than flip-flops.

4. Head to Toe in Polyester

In summer, it’s usually hot enough already–our clothing doesn’t need to make us sweat even more. So, steer clear of 100-percent polyester items! These synthetic clothes are not breathable at all–and you can see and smell it pretty quickly. The same goes for footwear: Plastic is not a good idea!

The better choice in summer is natural materials like linen or pure cotton. Blouses, dresses, shorts, and more made from these natural fabrics are not only very trendy this summer, but they also offer comfort and feel light and airy on the skin. This stylishly solves the annoying sweating problem.

5. Leggings as Pants

We primarily want to see leggings in the gym. Somehow, they’re only a complete piece of clothing there; otherwise, the elastic piece hardly replaces pants. On weekends and for a quick trip to the bakery or walking the dog, we let them slide, but they don’t really contribute to a serious or business-appropriate outfit and are a true fashion mistake.

Admittedly, the biker short, the little sister of leggings, made a comeback a few years ago. A trend that thrives on contrasts: Simple short biker shorts pair well with elegant tops that should ideally cover the butt. For a business look, choose more stylish shoes that can have a heel.
