Essential Fashion Terminology, Acronyms, and Abbreviations for Apparel Designers

Fashion terminology can make a straightforward conversation sound complicated. A shop describes a hoodie as oversized, a fabric supplier quotes its GSM, and a collection is labelled SS or FW. These terms describe different things: fit, fabric weight and season.

This glossary explains common fashion terms, acronyms and abbreviations for shoppers, students and clothing designers. Use the searchable table below to look up a word, or start with the quick explanations and examples. Some factory shorthand varies between businesses, so always check a supplier’s key before approving an order.

Common fashion abbreviations at a glance

  • SS or S/S: Spring/Summer. On a garment specification, SS may instead mean side seam or short sleeve.
  • AW or A/W: Autumn/Winter. FW or F/W means Fall/Winter, using the US word for autumn. FW can also mean full width in a fabric specification.
  • RTW: Ready-to-wear: finished clothing sold in standard sizes.
  • GSM: Grams per square metre, a measure of fabric weight for a given area.
  • MOQ: Minimum order quantity. Ask whether it applies to each style, colour or the whole order.
  • SKU: Stock keeping unit: a retailer’s identifier for a product variant, such as a particular size and colour.
  • TTS: True to size. It is a fit description, not a guarantee that all brands use the same measurements.
  • OOTD: Outfit of the day, commonly used in social posts.
Fashion Acronyms, Abbreviations, and Terminology for Designers
A clothing designer needs to know the lingo and fashion vocabulary

Abbreviation, acronym or initialism: what is the difference?

An abbreviation is any shortened form of a word or phrase. An acronym is an abbreviation pronounced as a word, such as CAD (computer-aided design). An initialism is read letter by letter, such as GSM or MOQ. In everyday conversation, people often call all of these acronyms.

The distinction matters less than context. “SS collection” usually refers to spring/summer, while “measure along SS” on a technical drawing may refer to the side seam. Spell out an unfamiliar abbreviation when you first use it in a tech pack or supplier email.

How to use the terms in practice

Reading a clothing description

“Oversized, garment-dyed, 300 GSM cotton jersey” tells you three separate things. Oversized describes the intended silhouette; garment-dyed means it was dyed after construction; and 300 GSM describes the fabric’s weight per square metre. None of those details alone proves that the garment is well made.

Jersey describes a knitted fabric construction, while cotton describes a fibre. A fabric can therefore be both cotton and jersey. Our guide to clothing materials and fabrics explains that distinction in more detail.

Asking a supplier for a quote

A useful enquiry might say: “Please quote for this style in two colourways. Is the MOQ per colour or across the order? Please confirm the fabric GSM, sample cost and production lead time.” That is clearer than sending a string of abbreviations without specifying what you need.

A tech pack brings the requirements together. The BOM lists the materials and components, while the POM measurements show where and how the garment should be measured. Include tolerances so the factory knows the permitted variation.

Checking fit before ordering

Body measurements and finished garment measurements are different. The space between them is called ease. A relaxed garment generally has more room than a close-fitting one, while some stretch garments are designed with negative ease.

Compare the retailer’s measurements with a similar garment you already like, and check whether the chart describes the body or the clothing. See our guides to measuring yourself for online clothes shopping and regular, relaxed and oversized hoodie fits.

Fashion terms that are easy to confuse

  • Vintage and retro: vintage refers to an item from an earlier era; retro describes a look inspired by the past and can include newly made clothes.
  • Bespoke and made-to-measure: bespoke generally starts with an individual pattern; made-to-measure adapts an existing one.
  • Fabric weight and quality: heavier does not automatically mean better. Weight needs to suit the garment, alongside construction, finishing and comfort.
  • Couture and haute couture: couture is widely used for high-end dressmaking; haute couture is a protected French designation, not simply a label for expensive clothes.
  • Organic and chemical-free: organic describes an agricultural standard. It does not mean a textile has never been processed with chemicals.

For practical buying checks, read our guide to spotting well-made clothes. For washing and drying instructions, use our separate clothing care symbols guide.

For specialist definitions, consult Cotton Incorporated’s textile glossary and CottonWorks. Certification names can be checked with Textile Exchange and GOTS. The Fédération de la Haute Couture et de la Mode explains the haute couture designation. For shipping agreements, use the ICC’s Incoterms explanations rather than relying on an abbreviated price quote.
