Stepping into summer calls for a wardrobe reset, and who better to guide the way than renowned designer Zac Posen? Known for dressing A-listers and shaping red carpet trends, Posen shares his discerning eye, offering fresh insights on styles to retire and standout pieces to embrace.

Why Your Summer Wardrobe Needs an Update

Fashion is not just about following trends; it’s about capturing the spirit of the season and expressing individuality. According to Zac Posen, making room for new essentials is just as important as knowing which items have outstayed their welcome. From dresses to accessories, updating your collection means curating pieces that celebrate both comfort and sophistication.

What to Toss: Outdated Trends to Leave Behind

Pared-back elegance replaces over-the-top statements this summer. Posen identifies the styles ready for retirement, helping you curate a more contemporary and stylish wardrobe:

Dresses with excessive cut-outs: Posen proclaims, “overexposure is dead.” This season, subtlety/coverage wins over revealing designs.
Chunky platform shoes: Streamlined silhouettes look fresher and more sophisticated.
Super skinny jeans: Wide-leg or relaxed-fit pants provide a modern, comfortable alternative.
Low-rise everything: High and mid-rise waists offer a more flattering and current look.
Heavy, layered jewelry: Exercise restraint—opt for delicate, thoughtfully placed accessories instead.
Logomania pieces: Loud, logo-drenched clothes feel dated in a season favoring understated luxury.
