How to Measure
To ensure you select the correct size from Simmi, please follow these measurement guidelines. Use a soft measuring tape and wear minimal clothing for accuracy. Measurements should be taken in the evening when feet are slightly swollen, as this represents their typical size throughout the day.
- Shoe Size — Foot Length: Stand barefoot on a flat surface with your weight distributed evenly. Measure from your heel to the tip of your longest toe (usually your big toe). Record the measurement in centimetres. Compare this measurement to the foot length column in the shoe size chart below.
- Clothing — Bust/Chest: Wrap the measuring tape around the fullest part of your bust, keeping the tape parallel to the ground and snug but not tight. Make sure the tape sits under your arms and spans across your shoulder blades. This measurement is crucial for determining your general clothing size.
- Clothing — Waist: Measure around your natural waistline, which is typically the slimmest part of your torso. This is usually the point where your body creases slightly when you bend forward, or where you naturally wear your trousers. Keep the tape comfortably snug without pulling tight.
- Clothing — Hips: Stand with your feet together and measure around the fullest part of your hips and bottom. The tape should be parallel to the ground and snug but not restrictive. This measurement is important for assessing the fit of trousers, skirts, and casual wear.
- Hoodies and Sweatshirts — Shoulder Width: Measure across the back of your shoulders from shoulder point to shoulder point. For a comfortable fit in hoodies and sweatshirts, this measurement should be close to the shoulder width listed in the casual size guide.
- Casual Wear — Length: For hoodies, measure from the top of your shoulder (at the neck seam) straight down to your preferred hem length. For sweatshirts and jumpers, measure from the shoulder to hip length for a standard fit. Simmi provides specific length measurements for hoodies (57–64 cm) and sweatshirts (65–72 cm) across all sizes.
- Joggers — Waist and Inseam: For cuffed joggers, measure your waist as described above. For inside leg length, measure from the top of your inner thigh at the crotch down to your ankle. Simmi's cuffed joggers have inside lengths ranging from 102–108 cm, whilst wide-leg joggers range from 74–76.5 cm.
- Shorts — Length: Measure from your natural waistline down to where you prefer your shorts to end. Simmi's shorts range from 35.5–42.5 cm in outside length across sizes XXS to 3XL.

Simmi Footwear — Product-Specific Guidance
Heels, Boots & Shoes: Simmi's footwear collection primarily comprises heels, ankle boots, knee-high boots, and statement shoes. The brand is renowned for bold, fashion-forward designs that often incorporate decorative elements, metallics, and eye-catching colours. All Simmi shoes are sized using UK sizing, which provides excellent consistency across the collection. Most customers find that Simmi shoes fit true to size. However, the brand offers several specific style categories that may have slight variations:
- Heels: Simmi heels range from kitten heels (approximately 5 cm) through to sky-high stilettos (10 cm or more). Remember that heel height is measured from the point where the heel meets the shoe upper, not from the sole. If you're new to higher heels, consider starting with styles in the 5–7 cm range and working upward as your confidence increases.
- Ankle Boots: Ankle boots typically fit true to size. However, if you have a wider calf or fuller ankle, you may need to consider a half size up or look for styles specifically described as having a relaxed fit through the leg.
- Knee-High & Over-The-Knee Boots: These styles benefit from accurate calf measurements. If sizing between UK sizes, consider trying the larger size if you have a calf width greater than average, as boots cannot be easily adjusted once purchased.
- Slip-On & Loafer Styles: These may fit slightly more generously in the toe box than other styles. If between sizes, you may find the smaller size sufficient.
Sizing Tips for Simmi London
- Check Product-Specific Reviews: Simmi products vary in fit, even within the same size category. Always read customer reviews on product pages before purchasing, as reviewers often mention whether items run small, large, or true to size. This is particularly important for footwear styles with unique shapes or tight-fitting designs.
- Take Advantage of Free Returns: Simmi offers free UK next-day delivery on orders over £75 and accepts returns through Klarna, PayPal, and Clearpay. If you're uncertain between two sizes, order both and return the one that doesn't fit. This is especially recommended for shoes where fit is critical to comfort and wearability.
- Measure Your Feet in the Evening: Feet naturally swell throughout the day and are largest in the evening. Measure your foot length in the late afternoon or evening for the most accurate sizing. This is particularly important when ordering heels, as tight-fitting shoes can cause discomfort during extended wear.
- Compare Actual Measurements, Not Just Size Labels: Simmi provides detailed measurements for casual wear items (hoodies, sweatshirts, joggers, and shorts) in centimetres. Rather than relying on size labels alone, compare your own measurements to these specifications. A size M sweatshirt may have shoulder width of 58.5 cm, which may or may not suit your frame depending on your shoulder width.
- Account for Style Variations in Casual Wear: Simmi's hoodies, sweatshirts, joggers, and shorts each have distinct fits and proportions. A sweatshirt may fit differently than a hoodie despite both being marked size M, as hoodies have broader shoulders (71 cm in size M) compared to sweatshirts (58.5 cm in size M). Always check the specific product category sizing.
- Know Your Shoe Preferences: If you prefer your heels to feel snug around the ankle and ball of the foot, Simmi heels in your standard UK size should work well. However, if you have particularly narrow feet or prefer a looser fit, you might need to size down. Conversely, those with broader feet may find a half size up more comfortable, especially in pointed-toe styles.
- Factor in Outfit Pairing: When ordering joggers or shorts, consider what you'll typically wear them with. If you prefer them paired with oversized hoodies, you might opt for a size down in the joggers to balance proportions. If you prefer a more relaxed silhouette overall, the wide-leg joggers in your standard size will provide the contemporary aesthetic Simmi is known for.
- Understand EU Sizing for International Orders: If ordering from outside the UK, Simmi provides EU size equivalents. Remember that EU sizes differ from UK sizes by approximately 30–32 points (e.g., UK size 6 equals EU size 39). Always double-check conversions to avoid ordering the wrong size.
- Consider Seasonal Variations: Heel heights and boot cuts may vary seasonally. Summer collections may feature sandals and flat styles, whilst autumn collections expand heel heights and introduce knee-high boots. If you're ordering out of season, be aware that size availability may be limited and stock may run small in popular sizes.
- Monitor the Size Guide for Updates: Simmi occasionally updates its size charts and may refine measurements or introduce new size categories. Before making a purchase, check the official Simmi London website at simmi.com to ensure you're referencing the most current sizing information, particularly if you're reordering a style you've purchased previously.
Frequently Asked Questions About Simmi Sizing
Do Simmi heels run small or large? Most Simmi heels run true to size. However, this varies by individual style, and some customers report that pointed-toe heels may feel slightly snug. Always consult product reviews to understand how a specific style fits.
What is the difference between Simmi's UK and EU sizing? Simmi uses UK sizing as its primary system, with EU conversions provided for international customers. There is no perfect conversion between the two systems due to different measurement methodologies. UK size 5 corresponds to EU size 38, UK size 6 to EU size 39, and so forth, increasing by one EU size for each UK size increment.
Can I return items to Simmi if they don't fit? Yes. Simmi accepts returns for unworn, unwashed items in original packaging. Returns are free within the UK and can be processed through various payment methods including Klarna and PayPal. Check the website for the current returns window (typically 28–30 days).
How do I know which casual wear size to order? Refer to the specific measurement charts for hoodies, sweatshirts, joggers, and shorts provided in this guide. Compare your own measurements (shoulder width, chest, waist, length) to the corresponding size. This is more reliable than relying on size labels alone.
Are Simmi shoes unisex? Simmi primarily produces women's footwear. The brand specialises in women's shoes and does not currently offer significant men's or unisex sizing in its core collection.
Do Simmi heels come with a size chart? Yes. Each product page includes specific sizing information and often photographs showing heel height measurements. Always check the individual product page before purchasing, as heel heights and fits may vary between styles.
