Sizing Tips
- Each product listing states the size range (e.g. "One Size 8–18") — always check this before purchasing.
- If you are between sizes or have a larger bust/hips, we recommend sizing up or choosing an 8–20 style.
- Our fabrics are carefully selected for stretch and comfort — most styles have a good amount of give.
- Still unsure? Feel free to contact us and we'll be happy to advise!
