Styling Physician Endorsed Hats is mostly a question of proportion, and the rest follows from there. One piece should lead and the rest should stay quiet; two competing pieces read as an accident. Proportion does more than colour: volume on top wants something narrow below, and the reverse. Hat sizing is a circumference in centimetres. Measure once and you never guess again. The groups below run from the decision that matters most to the ones you make afterwards.

What decides this is crown depth, brim width and circumference. Everything else is preference. Two from the first group show the range: Casablanca's White Beaded Crochet Hat at $250, and Casablanca's Stripe Crochet Hat at $180. The first is the considered buy; the second is the one to start with. Hat sizing is a circumference in centimetres. Measure once and you never guess again. A higher price mostly buys materials and finishing, and occasionally it buys nothing at all.

A hat commits the whole outfit. Keep the rest simple. From the second group, whitefoxboutique.com's Time To Travel Cap Navy/Cream ($25) is the one that earns its place, because it works in more than one context without being restyled. The third group is smaller and deliberately narrower, hats, for the decisions you make after the main one. None of this needs the whole group. One piece from each is usually enough.

There are 20 hats here from 14 brands, $25 to $250, all in stock when this was written. We would not buy all of them, and neither should you. whitefoxboutique.com's Time To Travel Cap Navy/Cream at $25 is the low-risk way in, and Casablanca's White Beaded Crochet Hat at $250 only makes sense if this is a category you already use constantly. On physician endorsed hats specifically: the difference between the top and the bottom of this list is real but smaller than the price gap suggests. Nothing here is included because it is famous, and price is not used as a proxy for quality anywhere on this page. If you take one thing away: one considered purchase beats three hedged ones.
