Does Monsoon Run Big? Your Complete Monsoon Sizing Guide

The Truth About Monsoon Sizing

As someone who's been styling women for over a decade, I can tell you that Monsoon is one of the more consistent brands on the high street—but 'consistent' doesn't mean 'identical across all pieces'. The brand generally follows UK high street sizing standards, but their romantic, artisan-inspired designs mean certain styles can catch you off guard.

Most of my clients find they can stick to their usual size in Monsoon, and many even size down, particularly in their signature flowing dresses. The brand designs with curves in mind, creating pieces that skim rather than cling, which is why their sizing feels more generous than brands like Zara or COS.

How Different Monsoon Pieces Actually Fit

Dresses: The Monsoon Signature

Monsoon's bread and butter—their romantic dresses—typically run true to size with a generous cut through the body. However, watch out for structured bodices or occasionwear with boning. These pieces can feel snug, especially if you're fuller through the bust or ribcage. I always recommend sizing up for fitted wedding guest dresses or anything with a defined waist seam.

Tops and Blouses

Generally quite forgiving and often on the looser side. Their flowing blouses are designed for comfort and movement, so stick to your usual size unless you prefer a more fitted look.

Trousers and Skirts

True to size, but pay attention to waistbands. Non-elasticated waists can run snug, whilst their newer styles with stretch waistbands are more forgiving.

Outerwear

Designed with layering in mind, so these pieces typically run true to size or slightly roomy—perfect for popping over knitwear.

Fabric Matters: Your Fitting Cheat Sheet

Here's where my professional experience really comes in handy. Monsoon uses various fabrics, and each behaves differently:

• Woven viscose and cotton: Structured with minimal stretch—size up if between sizes
• Chiffon and silk-feel fabrics: Flowing and forgiving, stick to your usual size
• Jersey and stretch fabrics: More accommodating, you might even size down
• Lined occasionwear: Often fitted through the bodice—consider sizing up

Brand Recommendations for Perfect Sizing

Independent Brands Worth Discovering

Brora offers luxury knitwear and separates with Scottish craftsmanship and sizing that's particularly generous through the body—perfect if you find Monsoon's structured pieces too fitted.

My Professional Sizing Tips

When shopping Monsoon, always check the fabric composition first. If it's a woven fabric with no stretch, I recommend ordering your usual size plus one size up if you're between sizes. For jersey or stretch fabrics, stick to your normal size.

Pay particular attention to bust and hip measurements on structured pieces. Monsoon tends to design for a more traditional hourglass figure, so if you carry weight differently, factor this into your sizing decisions.
