Sizing Considerations by Item Type
  • Maxi Dresses & Robes: Highly accommodating. A size XS can comfortably fit a UK 6–12. If you are petite or do not want the fabric to overwhelm your frame, sizing down is recommended. 

  • Denim & Structured Pieces: Fit much closer to standard numeric sizing. For tailored items or pants, customers often recommend sticking to your usual size or sizing up for comfort. 

  • Tops & Blouses: Spell offers styles ranging from breezy, oversized smocks to cinched, elastic-gathered tops. If you have a larger bust, you may want to size up in structured or button-front blouses.
