The Maroon floral cotton-linen maxi is offered in One Size even though its title says plus size. The listing supplies three figures: 144 cm bust, 132 cm length and 65 cm raglan sleeve. Those are useful reference points, but a single size label cannot establish how the waist, hip and arm opening will fit.

Build a reference envelope

Find a loose maxi you can move in. Record its finished bust circumference, total length and sleeve path, using the same measurement origins once the seller clarifies them. Ask if 144 cm is a finished garment bust or a body recommendation. A roomy bust number does not tell you the minimum waist or hip width on an A-line or gathered silhouette; request both flat measurements at named distances below the bust.

Measure raglan reach correctly

The 65 cm sleeve is labeled raglan, so it may start near the neckline instead of a conventional shoulder seam. On your reference dress, measure from the neck point to the cuff and also note upper-arm opening. Ask for a photo showing the start and end of the seller’s 65 cm tape. Comparing a set-in sleeve from the shoulder seam with a raglan number would mix two methods.

Place the hem and assess fabric

Mark 132 cm from the confirmed starting point on your reference dress and check the hem with shoes. The source describes a cotton-linen fabric but omits percentages, lining and opacity. Ask for a fabric label and an image against a contrasting underlayer if those details matter. “One Size” remains one option with missing dimensions, not a promise of universal fit.
