I designed to fit anyone that wears a Teen/Junior size M to L shirt. Cup size fits A-C with roughly a 32- 38 measurement around. There are some versions that can be made to make it fit better for some. These versions are noted in the pattern. Please if you have any questions, comments or need assistance on clarifying instructions in the pattern feel free to contact me. I would also like to ask if you make this or any of my other designs post picture on my facebook page Jen’s Crochet Creations
