Forget the 'wrong shoe theory': This summer you'll have to 'make a mistake' with your bag!

If you've been online in the past year, you've probably heard of the "mismatched shoe theory" that stylist Allison Bornstein made viral. The idea was simple: you wore a pair of shoes that (intentionally) didn't match the rest of your outfit. This contrast created an " effortlessly cool " effect, and the results were truly eye-catching.

But while the "wrong" shoes continue to hold their place in fashion, this summer a new concept is taking hold that we're calling the "wrong bag theory."

And no, we're not talking about some weird or super trendy bag, but about the straw bag, or more precisely the raffia bag. That bag that we usually associate with the beach, sand, and sunshine, is now being styled in the city, for breakfast with friends, daily coffee, or even casual dinners.

So, the bag that once held sunscreen, a book, and sunglasses is now part of combinations with jeans, linen shirts, or elegant dresses.

Here are some of the most fantastic combinations you can make:

Bust dress + Headscarf + Long strap bag

White linen shirt + Baggy jeans + Flip flops + Giant tote bag

Printed blouse + Pleated jeans + Ballerina flats + Tote bag

Colorful blouse + Three-quarter pants + Flat sandals + Handbag
