Yes. Yoga is for everyone.
The bigger question is if your teacher is right for everyone? A properly trained yoga instructor should have the knowledge to teach all body shapes, levels of experience and ages.
If you have special needs, for example you are pregnant, you will want to search for a teacher that is certified to teach for your special requirements. Make sure you ask the questions that fulfill your needs as you are ultimately your best teacher. You will know if the person you choose to guide you through your journey of yoga is right for you.
Ask, listen and make your choice.
