Fashion Influencer Mollie Campsie has shared her easy style rule that guarantees the ideal smart-casual ratio for perfect outfit combinations. 

Mollie, 31, who was once a student at Nottingham University, shares regular tips and style inspiration to her 252,000 followers on Instagram.

The rule requires the pairing of two smart garments and two casual garments which when combined create the perfect ratio for an effortless, chic outfit. 

In her new reel, which has over 79,000 views, she explained her rendition of the two-by-two rule.

Mollie said: “This is the two-by-two outfit formula I think everyone should try.

The example includes pairing tailored trousers and a blazer with more casual counterparts such as a plain t-shirt and converse trainers. 

“Together, it just works.”

She continued: “Two items are smart…two items are casual.

“Together, it just works.”

This concept, although seemingly simple, is the new golden rule for mastering the perfect smart-casual aesthetic.

The smart-casual hype, which is increasingly popular amongst Gen Z has branched off into various fashion subcategories like the “Scandi Style” which consists of essential, neutral items that can pair with anything.

Comfortable pieces that are deemed less formal are reworked into outfits to compliment tailored pieces, for a put-together, effortless look.   

Smart-casual has also become a practical approach towards fashion during recent times, particularly since the introduction of hybrid and remote working, where comfort is key.

According to a study conducted by Marks & Spencer in 2016, the average woman will spend 17 minutes trying to find an outfit for work each morning.

Since then, the introduction of new trends which happens more frequently due to social media popularity, has meant it is more challenging to establish individual style.

The two-by-two formula is a game-changer as it simplifies the way you view your wardrobe.
