Basic Blazer
By this point it should be no surprise that I LOVE blazers! Herringbone, navy, basic black, elbow patched, I love them all and think you can never have too many. That said, if I had to choose only one blazer forever it would be a basic black or navy number that can be worn with everything else in my closet. When choosing your perfect, year-round blazer I recommend finding one in a lightweight wool and a neutral color that compliments the most items in your closet.
Also, while gold buttons are nice I would recommend starting out with simple, understated buttons. That way, you can wear your topper without worry that the buttons will compete with anything else in your outfit.
