What is Sizing Like at Champion?

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

Champion runs large — particularly in its core sweatshirts, hoodies and joggers — and most UK women will want to size down at least one size from their usual, especially given the brand uses US sizing as its baseline.

I've been obsessed with Champion for years, long before it had its big fashion moment. I bought my first reverse weave hoodie a while back and made the classic mistake of ordering my usual size. It arrived looking less "effortlessly oversized" and more "borrowed from a much larger person." A swift exchange for a size down and it was perfect — that thick, structured fabric sitting just right. It's a lesson I've passed on to nearly every client since.

How Champion Sizing Actually Works

Champion is an American brand through and through, and their sizing reflects that. Here's what you genuinely need to know:

• Size down by one for the classic reverse weave hoodies and crew-neck sweatshirts — these are cut with a deliberately roomy, boxy silhouette, and the fabric has substantial weight to it.

• Joggers and sweatpants also run generous, particularly through the hip and thigh. If you're between sizes, go smaller.

• T-shirts and cropped styles tend to be more true to size, though still on the relaxed side.

• Women's specific fits (labelled "Women's" rather than unisex) are cut closer to the body and generally sit more true to your usual UK size.

• If you're shopping the unisex or men's styles — which many women do for that oversized look — drop at least one to two full sizes.

The Fabric Makes a Difference

One thing that sets Champion apart from your average gym brand is the quality of their heavyweight fabrics — particularly the reverse weave construction, which was originally designed to stop the fabric from shrinking lengthways. What this means practically is that these pieces don't lose their shape after washing, but they also don't stretch out to accommodate you if you've gone a size too big. The fit you buy is the fit you keep, so getting the right size from the start really does matter here.

The lighter-weight pieces — their jersey tees and lighter hoodies — behave more like standard jersey and are a little more forgiving. But for the hero pieces? Size down and trust the process.

Styling Champion — It's Not Just for the Gym

I know some people still think of Champion as purely workout gear, but I'd push back on that entirely. Styled well, it sits very comfortably in the smart-casual space. Here's how I'd wear it and how I style clients:

• The reverse weave hoodie tucked slightly at the front into wide-leg trousers with loafers = effortless off-duty dressing. One of my go-to combinations for clients who want to look put-together without trying too hard.

• Cropped Champion sweatshirt with high-waisted tailored trousers and a structured bag — streetwear meets polish.

• Champion joggers are genuinely one of the most wearable casual pieces going. Style them up with a fitted blazer and trainers for that elevated sports-luxe look.

• For layering, the classic crew neck sweatshirt works beautifully under an oversized leather or denim jacket.

High Street Alternatives to Shop Alongside Champion

If you love the Champion aesthetic but want to mix your wardrobe up or find pieces that sit in the same casual-cool space, here's where I'd head:

• Lululemon — if you want elevated athleisure that crosses into everyday wear beautifully. Their Scuba hoodies in particular are brilliant quality and size consistently true.

• Sweaty Betty — a fantastic UK option for sportswear that doesn't look like sportswear. Their fabric quality is exceptional and sizing is reliable.

• Gymshark — more fitted and performance-focused than Champion, but great for mixing into a casual wardrobe at a very accessible price point.

• Abercrombie & Fitch — their Essential Hoodie range directly competes with Champion for quality and wearability, and sizing is much more consistent for UK shoppers.

• Urban Outfitters — stocks Champion itself, but also their own BDG line which offers similar oversized sweatshirt vibes at a competitive price.

• Calvin Klein — for the minimalist logo sweatshirt and jogger look. Sizing is generally more European-aligned, making it easier for UK shoppers to navigate.

• Tommy Hilfiger — brilliant for that classic American sportswear heritage look; sizing is reliable and translates well to UK sizing with no drama.

Premium & Designer Options

If Champion's look is what you love but you want to invest at a higher level, these are the brands worth exploring:

• Varley — a premium activewear and lifestyle brand that's firmly in the "elevated Champion" territory. Their sizing is consistent and the quality is genuinely exceptional. Worth every penny for the lounge and casual pieces.

• Adanola — a London-based independent brand that has quietly become one of the most talked-about athleisure labels in the UK. Their oversized sweatshirts and matching sets are beautifully made and size true. A brilliant left-field pick if you want something a little different from the mainstream.

• At the luxury end, Max Mara do a brilliant line of high-end leisurewear and casual knits — when you want the relaxed silhouette of a Champion hoodie but in cashmere, essentially.

My Final Verdict on Champion Sizing

Champion is worth every bit of the cult status it's earned, but don't go in blind on sizing. Size down, check whether you're shopping unisex or women's specific styles, and remember that the heavyweight pieces are intentional — that's the whole point of them. Once you nail your size, these are pieces that will genuinely last you years. My original hoodie is still going strong, which in the world of fast fashion is saying something.
