The short answer on Types of Shoes: pick one anchor piece, keep the palette to two colours, and let the shoes decide how formal the whole thing reads. Proportion does more than colour: volume on top wants something narrow below, and the reverse. Repeat one element, a metal, a texture or a colour, and an outfit looks deliberate. A strap across the widest part of the foot is what stops slipping, not a tighter buckle. The groups below run from the decision that matters most to the ones you make afterwards.

What decides this is strap placement, footbed and heel height. Everything else is preference. Two from the first group show the range: fahertybrand.com's Kyma Kea Square Sandal - Natural at $89, and Nobody's Child's Brown Suede Double Strap Sandals at $49.97. The first is the considered buy; the second is the one to start with. A moulded footbed takes about a week to break in and then lasts years. A strap across the widest part of the foot is what stops slipping, not a tighter buckle. A higher price mostly buys materials and finishing, and occasionally it buys nothing at all.

A flat sandal reads dressier with a longer hem. From the second group, nobodyschild.com's Alohas Cream Rife Crochet Leather Sneakers ($102) 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, boots, 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 pieces here from 13 brands, $56 to $1100, all in stock when this was written. We would not buy all of them, and neither should you. Nobody's Child's Black Leather Strappy High Heels at $67 is the low-risk way in, and La Garçonne's Ella Silk Kitten Slingback at $1100 only makes sense if this is a category you already use constantly. Read as a set, they get you close to Types of Shoes without any single purchase being compulsory. 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: pay for the thing that touches your body and economise on the thing that sits on top of it.
