How to Measure for RIANI Clothing

If you don’t know your personal measurements or you want to check the fit of the pieces from the table above, taking accurate measurements is key.

Follow our stylist’s steps below…

If you’re finding it difficult to take your measurements, our stylists suggest getting someone to help you. Alternatively, you can visit our store, and we will be happy to help you.

Measuring Your Bust

To measure your bust yourself, stand up straight and wrap a measuring tape around the fullest part of your bust, keeping it parallel to the floor.

Ensure the tape is snug but not tight and doesn’t compress your bust.

Breathe out naturally before taking the measurement. It’s helpful to do this in front of a mirror to ensure the tape stays level all the way around.

Record the number where the tape meets its end for your bust size.

Measuring Your Hips

To measure your hips yourself, locate the widest part of your hipsusually around the area of your hip bones.

Keep your feet together for a more accurate measurement. Wrap a measuring tape around this part of your hips, keeping it parallel to the floor.

Ensure the tape is snug around your hips without being tight. Check the measurement on the tape where it overlaps to find your hip size.

Measuring Your Waist

To accurately measure your waist yourself, find the narrowest part of your waist, usually just above your belly button.

Stand up straight and relax your body; do not tuck in your stomach, as this will affect the measurement. Take a flexible measuring tape and wrap it around your waist, ensuring it remains parallel to the floor all the way around.

The tape should be snug but not tight enough to compress your skin. It is often easier to do this in front of a mirror to ensure the tape stays level.

Breathe normally and check where the end of the tape meets the rest of it to determine your waist measurement. Record this number as your waist size.

How Does RIANI Clothing Fit?

  • RIANI offers a range of fitted and casual options
  • Garments are generally true to size. Please refer to our sizing chart.
  • Our in-house stylists are able to help you if you’re between sizes or unsure of your size.

RIANI clothing is known for its sophisticated design and great fit, making it suitable for a wide range of body shapes and sizes.

The brand focuses on creating stylish yet comfortable clothing, ensuring that most items fit true to size.

RIANI offers everything from smart workwear, like tailored skirts and blazers, like the linen stretch blazer or the tweed mini skirt, which have more of a slim or fitted silhouette.

The label also has lots of relaxed silhouettes, such as cosy knits, like the short-sleeved zigzag sweater and the knitted stripe cardigan.

Many RIANI dresses have elasticated waists or tie belts, which makes the fit a little more flexible in terms of sizing. However, for the intended fit of the dress, we recommend sticking to your usual size.

Additionally, the brand uses high-quality fabrics that drape well and feel comfortable on the skin, like viscose, cotton, and linen. This adds to the overall fit of their clothing, making it look and feel flattering on all body types.
