Dinner Party Attire, decoded: the look is easier to assemble than it appears, and it hinges on proportion. Check where the waist seam sits on the model against your own proportions. A dress that fits the shoulders can be taken in anywhere else. One that does not, cannot. Lining is what stops a cheap fabric reading as cheap. The groups below run from the decision that matters most to the ones you make afterwards.

What decides this is shoulder fit, length and how the fabric moves. Everything else is preference. Two from the first group show the range: Byrdie Golf's Dockside Dress at $109, and Elie Tahari's Satin Tie Shirt Dress at $159. The first is the easy entry point; the second is where the money goes. Check where the waist seam sits on the model against your own proportions. A dress that fits the shoulders can be taken in anywhere else. One that does not, cannot. A higher price mostly buys materials and finishing, and occasionally it buys nothing at all.

A belt turns a shapeless dress into a deliberate one. Let the dress be the loudest thing you own that day. From the second group, shopakira.com's THE AFTERPARTY MINI DRESS ($90) 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, trousers, 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 16 brands, $50 to $1350, all in stock when this was written. We would not buy all of them, and neither should you. shopakira.com's MAKE A MESS KNIT MINI DRESS IN OLIVE at $50 is the low-risk way in, and aguabyaguabendita.com's Pluma Playa Mini Dress at $1350 only makes sense if this is a category you already use constantly. On dinner party attire 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: if you would not buy it at full price, you do not want it on sale.
