How to Become a Curve Model in the UK — TDA London

The Diversity Agency, London. Founded 2016. One of the largest dedicated curve rosters at any independent UK model agency, representing talent across UK fashion, beauty, e-commerce and lifestyle casting.

How to become a curve model in the UK

Curve modelling in the UK has changed faster in the last five years than any other corner of the industry. Brands that wouldn't touch a UK size 14 a decade ago are now building entire campaigns around curve casting. The infrastructure has lagged behind: most UK agencies still treat "Curve" as a category they tack onto a Mainboard rather than a board with its own roster, its own bookers, and its own briefs. That's the gap TDA's Curve board fills.

This guide exists because The Diversity Agency was founded in 2016 specifically to support categories of talent the wider UK agency landscape was failing. Curve was the loudest example. The article below is the guide TDA's booking team would have handed to those early applicants: what curve modelling actually means in the UK market, what bookers scan for in an application, and how to apply to the kind of agency that can build a curve career properly.

What "curve model" actually means in the UK

The starting point is UK size 14. That's the floor at most agencies, including TDA. Some agencies set it at 12. The ceiling is open — TDA signs curve models all the way through sizes 22, 24 and beyond. The category is defined less by a single dress size and more by the casting brief: curve briefs come from brands explicitly looking for talent outside the standard fashion mainboard size range, and they want the casting to look like a representative cross-section of their actual customer.

Worth flagging the terminology: in the UK market, curve is the standard term agencies use. Plus size is more common in the US. Curvy gets used informally but rarely on a contract. Aspiring models searching for representation will find more under curve model agency UK than plus size model agency UK.

Why the UK market is finally serious about curve

Five years ago, curve casting was largely confined to a handful of dedicated curve brands. Today it's standard practice across most UK fashion retail — Boohoo, ASOS, Manière De Voir, PrettyLittleThing, Simply Be, JD Williams, Yours Clothing and Marks & Spencer all build curve into their seasonal casting. Beauty brands are increasingly including curve in casting briefs even where the product isn't size-led. Personal care clients like Bodyform run campaigns where curve representation isn't a footnote — it's the brief.

The work is there. What's been missing is the agency infrastructure to support curve models properly: bookers who specialise, rosters that go beyond a token board, an honest signing process. That's the gap TDA was built to close.

Measurements and stats — what UK curve agencies want

Specifics matter. Here's what TDA's Curve board looks for:

• Dress size: UK 14 and up
• Height: usually 5'7" upwards for fashion castings. Lifestyle and commercial briefs are more flexible.
• Bust, waist, hips: measured in inches, not estimated. The agency wants the actual numbers.
• Proportion: a balanced shape — the ratio between bust, waist and hips — photographs well across the widest range of briefs.
• Skin tone, hair texture, ethnicity: TDA signs across the spread because clients cast across the spread.

Beyond stats, the casting decision comes down to face, confidence on camera, and proportion. There's no single curve body type. The strongest curve rosters cover a real range.

What TDA's bookers scan for in a curve application

Same checklist the booking team applies to any application, with three specific weightings for curve briefs:

1. Confidence in your own body, on camera. Curve briefs reward talent who occupy their own frame. A model who shrinks in the shot — pulls clothes loose, tucks an arm, angles to look smaller — won't be re-booked, no matter how strong the face. A curve model who stands straight and trusts the lens books seasons of work.

2. Skin and hair, same as any beauty brief. Curve casting doesn't lower the bar on these. Clear texture, even tone, healthy hair — all read the same on camera regardless of dress size.

3. Proportion across the body. What's consistently delivered for the curve models on TDA's roster: balanced bust-waist-hip ratios, defined shoulders, length through the neck and limbs. None of these are about being smaller. They're about how the body holds a frame.

What gets curve applicants rejected

The mistakes the booking team sees most often:

• Photos that try to hide the body. Loose clothing, baggy hoodies, sitting poses, angles from above. The brief is curve casting — digitals need to show the body, not minimise it.
• Heavy makeup and editing. Same rule as any beauty applicant. The brand wants to see what skin actually does.
• Aspirational stats. Send the real ones. A UK 16 should write 16. The casting brief is built around the shape the applicant actually has.
• Pitching as "almost curve". A UK 10 applicant hoping to be signed on Curve will be put on Mainboard if the stats fit — but the curve brief specifically calls for size 14 and up. Apply to the board that actually fits.

Why TDA's Curve board exists

TDA was founded in 2016 specifically because the agency landscape was failing entire categories of talent. Curve was the loudest example. The brief from clients was changing fast. The agency response was glacial.

The Curve board sits alongside Mainboard, Development, Classic, Hands, Modest and Family — seven specialist boards under one roof. That structure matters for curve applicants because it means there's a booker whose week is built around curve casting, a roster that already includes models worth sitting alongside, and a client list that books from Curve specifically rather than treating it as an afterthought.

How to apply to TDA's Curve board

The application form is at thediversity.agency/apply. It's the same form for every board — applicants select Curve in the board field. The agency needs:

• The four digital shots described in TDA's application guide: front head-and-shoulders, side profile, full body front, full body back.
• Full stats: dress size, bust, waist, hips, height, eye colour, hair, shoe size, age, location.
• A short note on location and any previous modelling work.

The booking team reads every Curve application that comes in. Responses go out within a week, yes or no.
