At Curve Theory, we specialize in plus-size clothing for curvy bodies, with styles that take into account shape, proportion, and comfort—so you feel as confident as you look.

• Check fabric and fit details – Whether an item is stretchy, structured, flowy, or fitted can affect how it will feel and fall.
• Look for product notes or reviews – These can give helpful insight into how a piece fits on real bodies.
• Reach out! – Our team is always happy to help with personalized advice so you can feel confident in your purchase.
• Prefer to pick up in person? – No problem! You can select in-store pickup at checkout, and we’ll notify you when your order is ready for pickup at our Mississauga location.
