When it comes to straw hats, the best time of year to buy them generally depends on the region of the world in which you live. In colder climates, winter is the best time to buy a straw hat, because people tend to wear hats more in the wintertime to keep their heads warm. In warmer climates, summer is generally the best time to buy a straw hat, since people tend to wear hats less in the summertime to avoid becoming too hot.That said, there are some general things to keep in mind when buying a straw hat. For instance, make sure that you buy a hat that fits well. A good way to test if a hat fits well is to put it on and then bend over; if the hat stays on your head when you do this, then it likely fits well. Additionally, be sure to choose a style of hat that suits your face shape; for example, if you have a round face, you might want to choose a style of hat with a wide brim that will help elongate your face.Ultimately, the best time of year to buy a straw hat depends on where you live and what the weather is like there. However, following these general tips should help ensure that you find a straw hat that is perfect for you!
