French Connection Sizing Guide: Does It Run Big? Your Complete Style Solution

The French Connection Sizing Reality Check
Having worked with French Connection pieces for over a decade, I've noticed a significant shift in their fit philosophy. The brand has embraced the relaxed, effortless aesthetic that's so on-trend right now, but this means their garments often run a full size larger than traditional UK sizing.
In my experience styling women of all shapes, I typically recommend going down one size in French Connection, especially if you prefer a more tailored fit. Their design team clearly favours that lived-in, slightly oversized look that works beautifully for the modern woman's lifestyle, but it can catch you off guard if you're expecting traditional sizing.
Breaking Down the Fit by Category
Dresses and Tops
This is where French Connection's generous sizing is most apparent. Their jersey dresses, in particular, are cut with significant ease through the body. I've found their wrap dresses and shirt dresses run especially large - perfect if you want that effortless, flowing silhouette, but size down if you prefer definition at the waist.
Their blouses and tees follow the same generous pattern. The relaxed fit works wonderfully for layering, but if you're petite or prefer a more structured look, definitely consider the smaller size.
Knitwear
French Connection's knitwear is where their sizing philosophy really shines. Their jumpers and cardigans are designed with that cosy, boyfriend-borrowed aesthetic. While this creates beautiful drape and movement, it means you'll often swim in your usual size. I always tell my clients to size down for a more flattering silhouette, unless you're specifically after that oversized look.
Trousers and Jeans
Here's where things get interesting - their bottoms tend to be more true to size, though still with a contemporary relaxed fit. Their wide-leg trousers and palazzo styles run generous through the waist and hips, whilst their skinny jeans are closer to standard UK sizing.
Style Recommendations: High Street to Luxury Alternatives

High Street Heroes
If you love French Connection's aesthetic but want more predictable sizing, try Zara - their European sizing runs similarly generous, perfect for that modern, relaxed silhouette. Mango offers excellent quality basics with consistent sizing that rivals FCUK's style direction. COS delivers that minimalist, architectural approach to dressing with reliable sizing throughout their range.
Whistles provides sophisticated pieces with a more tailored approach to contemporary sizing. Jigsaw offers timeless pieces with traditional UK sizing that fits true to size. For budget-conscious shoppers, H&M delivers trend-led pieces with European sizing similar to French Connection. Massimo Dutti brings that effortless European sophistication with consistent sizing across their collections.
Premium Picks
Step up to Reiss for impeccable tailoring with sizing that's consistent and true to form. Their pieces offer that same contemporary edge as French Connection but with more structured fits that work beautifully for professional settings.
Luxury Alternatives
For those special investment pieces, consider Isabel Marant - the epitome of Parisian effortless chic with sizing that's consistent with French standards. Ganni offers that same relaxed-yet-polished aesthetic with Scandinavian precision in their fits.
My Professional Sizing Tips
Always check the measurements, not just the size label. French Connection's size guide is generally accurate, but I recommend measuring yourself and comparing to their specific garment measurements online.
Consider the fabric - their cotton and linen pieces tend to run the most generous, whilst their synthetic blends are closer to true sizing.
Think about your styling goals. If you're after that effortless, undone look that French Connection does so well, their generous sizing works in your favour. But if you prefer more structure and definition, size down without hesitation.
