What Is Sizing Like at More Joy?

By Ella Blake — Fashion Stylist | Tellar Fashion Hub — Always honest, unbiased & unsponsored

More Joy sizing runs true to size overall, but almost everything the brand makes is deliberately cut with a relaxed, oversized silhouette — so if you're after a more fitted look, sizing down by one is often the smarter move. It's one of those brands where understanding the intended fit is half the battle.

I'll be honest — I bought my first More Joy sweatshirt without paying enough attention to this, grabbed my usual size, and ended up looking like I'd borrowed something from a much taller friend. Once I sized down, it was perfect: still relaxed, still cool, but actually shaped. Lesson learned.

About More Joy

More Joy was launched in 2019 by Scottish designer Christopher Kane and his sister Tammy as a playful, slogan-led offshoot of the Christopher Kane label. The brand offers an optimistic and fun approach to casualwear, converting fashion into a kind of playful freedom of speech — think bold logo tees, sweatshirts, and joggers in a signature red, white and black palette. It sits in that brilliant sweet spot between luxury and streetwear, and those "More Joy" and "Sex" slogans have become genuinely iconic. If you've been looking for a premium slogan piece that doesn't feel try-hard, this is it.

Note: More Joy pieces are intentionally oversized. If you prefer a closer fit, go one size down from your usual UK size.

Fit by Garment Type

The fit varies slightly depending on what you're buying, so here's a quick breakdown garment by garment:

Slogan T-Shirts: These fit true to size, but the cut has dropped shoulders and a boxy, relaxed shape by design. If you want it to skim your body rather than hang, size down once.
Sweatshirts & Hoodies: Slightly oversized with a boyfriend fit — the brand recommends taking your usual size. I'd still suggest sizing down if you're between sizes or don't want an extremely baggy look.
Joggers: These tend to be roomy through the leg with an elasticated waist, so true to size works well here. The relaxed fit is intentional and part of the aesthetic.
Caps & Accessories: One-size-fits-most generally applies. No sizing headaches here — just pick your colourway.

How Does More Joy Sizing Compare to Other Brands?

If you're used to shopping at, say, Zara or COS, you'll find More Joy runs noticeably larger in the body. It's a similar story to brands like Champion or Sporty & Rich — the oversized cut is deliberate, it's part of the cool factor, but it can catch you off guard if you just click your usual size without thinking. I'd compare it most closely to the kind of fit you'd get from a vintage-wash Ralph Lauren crewneck: roomy, relaxed, designed to be worn loose.

The quality is excellent — the cotton is substantial and the prints are crisp — so once you've nailed your size, these pieces genuinely last and look better with every wash.

My Sizing Verdict

✔ True to your regular UK size if you want the full oversized, relaxed look
✔ Size down one if you want a slightly more fitted, still-cool silhouette
✔ Between sizes? Always go down — the fabric has enough give
✔ Petite frames: An XS is genuinely very generous — consider sizing down where XS is the smallest option, or look for a specific "XS/S" if the brand offers it

How to Style More Joy

The beauty of More Joy pieces is that they do all the talking, so the rest of your outfit can be pared back. My go-to formula is the slogan tee tucked loosely into wide-leg tailored trousers with clean white trainers. It's that effortless designer-meets-off-duty energy that never looks overdone. Alternatively, the sweatshirt over a short floaty skirt is having a real moment right now — it's the kind of mix that feels thrown together but actually takes a bit of editorial nerve to pull off.

For the logo tee specifically: don't overthink it. Dark-wash straight-leg jeans, chunky loafers, a decent tote bag. Done. The piece earns its own keep.

High Street Alternatives to More Joy

If you love the slogan-led, relaxed luxury aesthetic but the price point isn't working for you right now, there are some genuinely brilliant alternatives:

Urban Outfitters — Brilliant for graphic and slogan pieces with a similar playful energy. Their BDG tees and vintage-inspired sweatshirts are well-priced and genuinely good quality for the cost.
Topshop — Still one of the best for bold graphic tees with a fashion-forward edge. Their oversized slogan sweatshirts have strong More Joy energy at a fraction of the price.
ASOS — Surprisingly strong for elevated casualwear with logo-adjacent pieces. Their own-brand range has improved considerably and the sizing options are excellent.
All Saints — If you want the dark, moody, slightly subversive end of the casualwear spectrum, All Saints does it brilliantly. The quality is closer to More Joy's level too.
Mango — Their streetwear-influenced drops have been impressive recently. Look for their graphic jersey pieces — they punch well above their price bracket.
COS — For a more minimalist take on the same relaxed aesthetic. Less slogany, more architectural, but with the same commitment to quality cotton basics in oversized fits.
Whistles — Slightly more grown-up in feel, but their relaxed jersey pieces and printed sweatshirts have a similar ease-of-wear quality that More Joy fans tend to gravitate towards.
Anthropologie — Great for offbeat, characterful pieces that feel a bit unexpected. Their graphic and slogan-style knits are particularly good.

Independent Brands Worth Knowing

Bella Freud — A genuine cult British brand known for her iconic slogan knitwear (think "1970" and "Je t'aime Jane" in intarsia knit). If More Joy appeals to you, Bella Freud is essentially the more literary, grown-up cousin. Adored by stylists, criminally underrated by the general public.
Rowing Blazers — A New York-based brand that's made a name for itself with bold, irreverent slogans on high-quality sportswear-inspired pieces. The polo shirts and rugby shirts in particular have a similarly cheeky tone to More Joy, with a preppy twist.

Premium & Luxury Alternatives

If you're happy to spend at a similar or higher level to More Joy, these brands scratch a similar itch:

Alexander McQueen — For bold, graphic statement pieces with serious designer provenance. The logo and slogan-adjacent pieces are beautifully made.
Stella McCartney — For elevated luxury casualwear with a conscience. The quality is exceptional, and the brand shares More Joy's playful approach to graphic design.
Raf Simons — If you want to go full deep-end into the art-meets-streetwear world that More Joy orbits, Raf Simons is the destination. Archive pieces in particular are iconic.
