I just finished crocheting this bralette. I followed the pattern by Shyler Crochets, and this video tutorial really took me from total wearables noob to novice in no time. I used one ball of Oh My Yarn Cotone Medio yarn in tree, and a size 5mm hook.
I highly recommend this pattern if you are also dipping your toes into the world of crocheted wearables. It is easy to follow. I was able to finish it in a couple of days.
Enjoy your new crochet project!
