This is a great idea--to add crochet motifs to an existing bra. I would leave the original cup in, because then you would end up with a crochet bathing suit top that wouldn't stretch and fall off when you wore it into the water!
Hand crochet top 100% cotton Available in A, B, C cup bra sizes Shipping: to USA - 12-20 days, to EU - 1-2 weeks, to Australia - 3 weeks. Hand wash and lay flat to dry. If you want to order other size, please convo me.
