Personal preference and comfort are the main considerations with fit however, a ballet leotard should fit snugly without digging in or restricting movement. It should sit flat against the body with no bunching or gaping. BODILE leotards are designed for a sculpting fit many with built in bust support. Check our sizing guide for detailed measurements. Please note fit will vary depending on the leotard cut, so please be sure to note the 'run size' on the product page for an accurate description.
