The short answer on What are Alt Girls is below, and the honest version is that it depends on two or three things rather than one. 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. 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: Lisa Says Gah's Valeria Double Layer Shirt - Caraway Stripe at $145, and Faherty's Paradise Pointelle Tank - White at $54. The first is the considered buy; the second is the one to start with. 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, Lisa Says Gah's Forager Jacket - Chocolate ($180) 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, jeans, 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 14 brands, $21 to $590, all in stock when this was written. We would not buy all of them, and neither should you. THATS SO FETCH's Joselyn Cut Out Blazer - Blue at $21 is the low-risk way in, and us.isabelmarant.com's Belvia Jeans at $590 only makes sense if this is a category you already use constantly. Read as a set, they get you close to What are Alt Girls 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: buy the one you can picture using this week, not the one you are saving for later.
