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.

Our guides are suggested size only, due to the high level of adjustability and different fabric constructions. Some pieces can adjust further than others and there may be difference between styles and seasons.

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 detergent formulated for silk fabrics, 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.
