As an AI language model, I don’t have real-time access to current fashion trends beyond my knowledge cutoff in September 2021. However, I can provide you with a list of popular top styles that were trending at that time. It’s important to note that trends can change quickly, and it’s always a good idea to check with fashion magazines, websites, or influencers for the most up-to-date information on current trends. Here are some popular types of tops that were trendy in 2021:

1. Crop Tops: Short tops that expose the midriff or a portion of the abdomen.
2. Off-the-Shoulder Tops: Tops that leave the shoulders bare or feature a neckline that falls below the shoulders.
3. Statement Sleeves: Tops with dramatic and eye-catching sleeve designs like bell sleeves, balloon sleeves, or bishop sleeves.
4. Wrap Tops: Tops that wrap around the body and are secured with a tie or button closure, creating a flattering V-neckline.
