About the Team
Meet Cathy
“I created Foundations Revealed to help us all work together to realize our costume and corsetry dreams.”

British costume artist Cathy Hay is the creator and publisher of Foundations Revealed, which was born out of a grand wish to help other dressmakers to connect with each other, stay inspired and positive, hone their skills together and realise their sewing dreams.

She is a member of both the Costume Society in the UK and the Costumer’s Guild West in the USA. Her own website is cathyhay.com.

Her first job was working at Shakespeare's Globe, and she has gone on to work on projects such as Wonder Woman, the Kingsman movies, Mary Poppins Returns, and Britannia.

Community Concierges



Maeri Certo is a corsetry & historical costuming enthusiast who dabbles in retro/pinup styling more often than historical dress. As a Foundations revealed Community Concierge, Maeri is excited to support this creative & caring corner of the internet and help other Stitchlings embrace their passions.

Her current passions include her millinery & costume design business Certain Sundries and expanding her personal collection of vintage-inspired clothing & lingerie.




Andrew is a Medieval History student studying at the University of St Andrews, but originally hails from California where he grew up on a horse ranch.

His crafting career began with an apprenticeship with a local saddle maker, where he worked restoring antique saddles and tack. Since getting interested in historical costuming, much of his research has revolved around recreating and testing historical equestrian wear and tack with the aid of his horses.




Brooklynne has a degree in fashion and costume design. After working for two fast fashion brands and a small opera house, she spent 12 years not touching her degree. Since recently reconnecting to her first passion of Victorian clothing she now works as a historically inspired dressmaker. As a Community Concierge for Foundations Revealed, Brooklynne can’t wait to help the creative geniuses that make up our community in finding what they need.
