LEO COSTELLOE (b. 1993, Canberra) is a London-based, Irish-Australianinterdisciplinary artist whose work explores the transient and sentimental nature of objects in contemporary culture. Drawing from lexicons of digital and historical femininity, adornment and craft, Costelloe’s sculptural practice uses glass, silversmithing, hair, flowers and found objects to recast familiar decorative and utilitarian signifiers and reframe objects’ presupposed meanings. This material dissonance imbues banal items with emotional resonance and subtle subversion, unsettling conventional ideas of decoration, utility, gender, and class.

Costelloe has presented solo exhibitions at NEVEN, London (2024), Ridley Road Project Space, London (2022) and Kupfer, London (2023). Their work has been featured in group exhibitions at CAIM, Slane Castle, Ireland (2025); NADA New York (2025); Matt Carey-Williams, London (2024); Studio West Gallery, London (2024); Indigo + Madder, London (2023); The Stanley & Audrey Burton Gallery, Leeds (2023); General Assembly, London (2023); Kupfer, London (2023); Photobook Gallery, London (2023); and Ridley Road Project Space, London (2022). Costelloe has worked with a variety of brands and institutions, including Monique Fei, ShowStudio, the British Fashion Council, and Dover Street Market New York. They were awarded the Swarovski Scholar Award (2020) after having been a finalist for the same in 2019. Costelloe graduated from Central Saint Martins with a BA (Hons) in Jewellery Design.
