Size guide

At Siren we are constantly looking to bring you the biggest and best collection of limited editions designs out there! However, sizing can vary among brands, and among styles. We try our very best to provide you with the most accurate sizing and fit information possible, which is why the description section in each product's profile includes any additional information that we believe will help you make an informed decision when shopping!
Most of our beautiful, hand crafted and limited edition knitwear is made one size only, due to our small production runs. We do still endeavour to make our numerous styles and designs available for everyone, so although a garment may have been made in one size, we put lots of care into making our garments with stretch; for example, being woven with pure cottons to provide you a versatile fit. In order to give you an indication of fit and sizing, we measure the length of every garment in each size and list the length under description in the product profile. In addition, we run a fit test of the small or equivalent size (size 8) of every garment we carry. This helps us to determine if the piece runs true to size, runs small, runs large, or has an oversized fit, and we let you know our findings under the description section!
If we say that a garment "runs large," or "runs small," and there is no further information shown in the description section, this means that the item consistently runs larger or smaller across all the measurements (bust, waist, hips). If the garment runs larger or smaller across some of the measurements, or if it runs larger or smaller consistently across the measurements but not across all of the sizes, we will also note this in the description section!
Whenever we determine that a garment "runs large, please size down", or "runs small, please size up", we have taken into consideration each specific measurement across all sizes. What that means is that if an item is labeled "runs large," that means it can fit up one equivalent size (for example, a 12 fits up to a 14). If there is no further information entered in the description section, the item runs consistently larger across all measurements. Our size chart below is also aimed at helping you to select the perfect size. We are dedicated to helping you find the perfect size and fit, so please contact us with your questions! We can provide specific product details, unique measurements, and fit recommendations if you need them.

How will I know if an item will fit me?

If you are unsure of how an item might fit you or are stuck to find out the size of the garment, the description section of the product page has more information about the garment. Important information about the product, such as whether the item has stretch, or runs big or small, will be included within its profile, and can help you with your decision (please see above). Also, please consider your comfort. If you are between sizes, order a size up or down based on the type of fit you prefer.
If you are stumped for a decision, please do contact us! 01618727887 & email at info@sirenlondon.com

All of our 'one size' knitwear can fit the following sizes unless stated otherwise:

How do I know if a one of a kind item will fit me?

One of a kind items often have unique sizing information. That's why every one of a kind garment sold on Siren is specifically measured for bust, waist, and hip fit. These dimensions are provided in the description section of each product page. Dimensions are given in inches and taken flat across the garment. The listed measurements do not include any stretch the item might have, nor do they correspond directly with the item's circumference. While it may seem unconventional to provide each item's specific measurements in this way, it is the most accurate way for us to help you determine fit with one of a kind garments. To best assess your fit, choose a garment that you already own and that fits you well. Lay this item flat and measure across the front. Then, compare your measurement with your desired garment's description information.

Bust 

To determine an accurate bust measurement, lay your measuring tool flat across the garment's front, just under the arms.
 

Waist

The waist measurement included in the description of a product's profile provides the garment's natural waist dimension - this is the most narrow part of your mid-section. For a dress's waist measurement, find the narrowest part of the garment (the waist line), and measure it. For pants or a skirt, measure the top of the garment to ascertain its waist.

Hip

Measure the widest part of a skirt or pants, below the waistband.

Length

For tops and dresses, measure from the top of the shoulder to the bottom of the garment. For pants and skirts, this is the measurement from the waist to the bottom.
