Studio Pia was founded with a fresh approach to sizing that is as much about aesthetics as it is about function. You will find adjustability throughout each and every piece we create: from our bra backs, which have an adjustability range of 10cm to fit across three band sizes, to our basques, bodysuits, suspenders and bottoms which all have a range of at least two dress sizes.

To find your perfect fit, simply locate your usual size on the charts below and and see which 'SP size' it converts to.

Make it Last

Studio Pia collections are constructed to a high quality using some of the finest materials, including cruelty-free organic peace silk, delicate embroidered tulle, and 24k gold plated zamak hardware.
Some natural imperfections may be found in the weave of the silk due to the nature of the material, as well as some slight colour variation as a result of the small-batch dye process used. Due to the dye requirements for natural fibres like silk, dark and bright colours may transfer to light coloured garments
Wash by hand in cool water with similar colours using a mild detergent, and then dry flat. Do not machine wash or tumble dry any Studio Pia pieces as this may damage your lingerie and shorten its life span. We also recommend washing and storing your delicate pieces separately to any items that might snag them, such as those with embellishment or hooks etc. Due to the dye requirements for natural fibres like silk, dark and bright colours may bleed during the first few washes.

For customers outside of the UK, please note that your order may be subject to import duties and taxes over which Studio Pia has no control, as they are levied by your tax and customs office. As the customer and importer of the goods, you will be responsible for these charges. Import duties or tax costs will be invoiced to you directly from the appointed forwarder. We recommend you contact your local customs authority to determine a landed cost price prior to purchase completion. Studio Pia is not responsible for any delays on goods that have been held back as a result of procedures carried out by your local customs authorities. Please email if you have any concerns about your order.

Studio Pia cannot accept any order cancellations once an order is dispatched or received at the customs point of the destination country.

We recommend staying up to date with the progress of your shipment in case there are any exceptions during transit. A signature is required for any goods delivered, at which point responsibility for the purchased goods is passed to you. If you request to waive the signature requirement, neither Studio Pia nor the courier company will hold any responsibility for a lost package. In the United States, all shipments are sent with a signed for service, however, couriers can legally deliver without requesting a signature.

If a package is marked as delivered but has not been received, Studio Pia will run a full investigation with our customer service team and the appropriate courier. In general, a resolution cannot be offered until a response is received by the courier, which can take several weeks.
