Johanna Ortiz Size Guide: US to UK Conversion and How the Pieces Fit

Johanna Ortiz is cut on US sizing at source. Coveti shows it converted to UK, so the size on the product page is the size you order. This guide covers the conversion, how the pieces actually fit, and the handful of styles where the shape changes the answer.

US to UK conversion

Letter sizing

Knitwear, swimwear and some loose tops run on letters rather than numbers, from XXS through XXL. Swim is cut XS to XL at source. Letter sizing on this label is generous through the body, because the shapes are designed to hang rather than to fit close.

Does Johanna Ortiz run true to size?

Yes, on the overwhelming majority of the collection. This is worth stating plainly because the clothes look oversized in photographs and buyers assume they should size down. They should not. The volume is cut into the garment. Sizing down fights the design and usually spoils the shoulder line, which is the part of a Johanna Ortiz piece that does the work.

The exceptions are a small number of styles where the house itself publishes a sizing note. Where it does, the note appears on the Coveti product page under Size and Fit, and it is the brand’s own wording rather than ours.

Shoes

Footwear runs the EU ladder, cut from 36 to 41 across the collection. As a rough conversion, EU 37 is UK 4, EU 38 is UK 5, EU 39 is UK 6, EU 40 is UK 7 and EU 41 is UK 8. Browse Johanna Ortiz shoes.

Accessories

Bags, jewellery, belts, hats and scarves are made in one size. Where the house publishes dimensions they appear in the product details on the page. Browse accessories and jewellery.

If you are between sizes

Take the larger size on anything with a structured shoulder, a fitted bodice, a blazer and a coat. Take the smaller size on a loose tunic, a kaftan and anything described as oversized, since those already carry ease. For a wrap silhouette with a self-tie waist, either size works because the tie adjusts.
