The short answer on Whistles Nicola Button Through Shirt: pick one anchor piece, keep the palette to two colours, and let the shoes decide how formal the whole thing reads. 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. The shoulder seam should sit on the bone, not past it. The groups below run from the decision that matters most to the ones you make afterwards.

What decides this is shoulder seam, sleeve length and opacity. Everything else is preference. Two from the first group show the range: The Couture Club's KNITTED RIBBED BUTTON THROUGH TOP - OFF WHITE at $92, and La Garçonne's Opto S Jersey Button Front Shirt at $291. The first is the easy entry point; the second is where the money goes. Hold it up to the light. Opacity is the thing product photography hides best. The shoulder seam should sit on the bone, not past it. A higher price mostly buys materials and finishing, and occasionally it buys nothing at all.

If the top is the point, keep everything below it plain. From the second group, 16Arlington's Fale Top in Jersey ($204) 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, tops, 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 tops here from 13 brands, $45 to $1050, all in stock when this was written. We would not buy all of them, and neither should you. Liverpool Los Angeles's 3/4 SLEEVE BUTTON FRONT TOP W/ RUFFLE DETAILS at $45 is the low-risk way in, and La Garçonne's Button-Down Cotton Shirt at $1050 only makes sense if this is a category you already use constantly. On whistles nicola button through shirt 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.
