One Size, Explained: How The Stripe Maxi and The Cardigan Actually Fit

One size is the size on two of our most-asked-about pieces — The Stripe Maxi and The Fine-Knit Cardigan — and it understandably raises the same question every time: whose one size? Neither piece is cut to a single body; each is cut to a construction that does the adjusting instead, a rib that stretches and a knit that's deliberately loose, and that's a genuinely different promise to a jean sized 8 to 18.

The Stripe Maxi is a ribbed column dress — cut to stretch, which is the whole mechanism behind the one size. A rib knit like this holds its shape until you put a body inside it, and then it does what ribs do: it closes in around whatever it meets, so it sits closer through the middle on a fuller frame and skims looser on a slighter one, without changing the column silhouette either way. The cap sleeve and the fine horizontal stripe stay where they are regardless — what moves is how much the fabric is asked to give between the shoulder and the ankle.

The Fine-Knit Cardigan works the opposite way — it's designed to be worn loose rather than to stretch to fit. On a smaller frame that reads as genuine volume, room to move inside it; on a larger frame, because it isn't a rib and doesn't have the same give, it sits closer to the body, more like a true layer than an oversized one. Either way it buttons to the throat and sits in a V at the neck, so how open or closed it looks depends on how many buttons you do up, not on the size on the label.

Neither piece has a second size to check yourself against, which is the honest trade-off of one-size: no chart, only the two garments' own construction and what you already know about how you like things to sit. If you tend to prefer more room, the cardigan is built to give it to you regardless of build; if you're after something closer, the maxi's stretch is already doing that job, most noticeably through the middle.

We'd rather say this plainly than leave it to a product photo to explain. One size on these two pieces means two different mechanisms doing the work, not one guess that happens to fit everyone the same way.
