Sizing questions
- Should I size up in kids clothing?
- Size up one step for jackets and sweaters so a layer fits underneath. Stay true to size for bodysuits, leggings and sleepwear.
- Do maternity sizes differ from regular sizes?
- No. Order your pre-pregnancy size — maternity patterns already include room for the bump. Sizing up usually causes gaping at the shoulders.
- What if the size is wrong?
- Every TiniCuddle seller offers a free size exchange within 30 days of delivery, and refunds are processed within 5 business days.
