I have noticed a lot of tops and tees with ruffled (fluttered) sleeves in the stores at the moment. It is way more fun to crochet a top like that yourself! The pattern of this top is written in 7 different sizes. The top is made with fine (2) weight yarn.
You can find the free crochet pattern of the All a Flutter Girl ‘s Top on the website of I Need It Crochet.
