Great Plains Sizing: Does It Run Big? The Honest Truth From a Stylist

The Great Plains Sizing Reality Check

Let me be brutally honest—Great Plains is one of those brands that keeps us stylists on our toes. Owned by French Connection, you'd expect some consistency, but their sizing tells a different story entirely. I've had clients who are a perfect size 12 in their midi dress struggle to get their size 14 trousers past their hips. It's maddening, but there's method to this madness once you understand the patterns.

Their tops and knitwear typically run a full size generous. If you're usually a size 12 at M&S (the reliable British sizing benchmark), you'll likely need a size 10 in most Great Plains tops. Their dresses follow a similar pattern—generous through the bust and waist, with enough room that you won't feel restricted.

The Trouser Trap: Why Great Plains Bottoms Run Small

Here's where Great Plains gets tricky. Their trousers consistently run 1-2 sizes smaller than their stated size, particularly around the hips and thighs. I've seen countless clients who fit beautifully into a Great Plains size 12 dress need a size 16 in their trousers from the same collection. It's not you—it's definitely them.

The issue seems to stem from their cutting patterns. Whilst brands like Zara (known for slim European cuts) and COS (minimalist Scandinavian fits) are upfront about their sizing philosophy, Great Plains appears to use different sizing charts for different garment categories without clearly communicating this to customers.

My Styling Strategy: How to Shop Great Plains Successfully

After working with this brand for years, here's my foolproof approach:

For tops and dresses: Order your usual UK size or even size down if you prefer a more fitted look. Their jersey dresses are particularly generous—perfect if you like that relaxed, effortless vibe that Great Plains does so well.

For trousers and bottoms: Size up by at least one size, sometimes two. Always check their specific measurements if available, and don't be afraid to order two sizes if you're unsure—their return policy is generally accommodating.

Brand Alternatives: Where to Shop When Great Plains Sizing Fails

High Street Heroes:

If Great Plains sizing isn't working for you, I consistently recommend Whistles for their reliable contemporary pieces with consistent sizing across all categories. Reiss offers similar aesthetic appeal with more predictable fits, whilst Mango delivers that effortless European style with better size consistency.

For basics that actually fit as expected, H&M Conscious range offers sustainable pieces with clear sizing, and Cos provides minimalist staples that run true to size. Don't overlook Great Plains itself for their knitwear—it's genuinely excellent quality when you get the sizing right.

Premium Picks:

Step up to Me&Em for foolproof contemporary pieces that fit consistently across their range—worth the investment for the sizing reliability alone. LK Bennett offers polished pieces with traditional British sizing that actually makes sense.

Independent Discoveries:

I'm obsessed with Beaumont Organic for their sustainable luxury basics with transparent sizing guides, and Kotn for elevated essentials that fit exactly as described—refreshing when you're used to Great Plains' guesswork approach.

The Fabric Factor: Why Material Matters for Great Plains Sizing

Great Plains uses diverse fabrics across their range, and this significantly impacts fit. Their cotton jersey pieces tend to run largest—expect generous draping that's perfect for that relaxed weekend aesthetic. Their structured blazers and tailored pieces run closer to true size, whilst anything with elastane or stretch will be more forgiving.

Always read the fabric composition before ordering. Natural fibres like their linen blend pieces will have less give, so sizing up might be wise if you're between sizes.

Why I Still Recommend Great Plains (Despite the Sizing Drama)

Here's the thing—when Great Plains gets it right, they really get it right. Their colour palettes are sophisticated, their prints are distinctive without being loud, and their quality is genuinely impressive for the price point. The brand has carved out a lovely niche for grown-up casual wear that doesn't sacrifice style for comfort.

Their seasonal collections consistently deliver pieces that work across age groups and body types—you just need to crack their sizing code first.
