Solange Knowles has delayed the launch of her latest Puma collaboration, in order to protest the Ferguson grand jury’s decision not to charge officer Darren Wilson, for the fatal shooting of Michael Brown in August.

[related]"To echo my feelings shared surrounding the outcome of the Michael Brown case, I have solely decided to postpone the release of my Puma collaboration originally scheduled to release this Friday November 28th to Monday December 1st. I am truly grateful for everyone's support and excited to share this collection with you soon… - Solange,” reads a post on the newlywed’s Instagram.

The singer and style icon was due to drop the Wild Wonders collection, her second for the sportswear brand, made in conjunction with designers Gerlan Marcel, Hisham Bharoocha and sister duo Darlene and Lizzy Okpo.

However, like many other stars, Solange is taking part in #BlackoutBlackFriday – a boycott on retail spending on the biggest shopping day of the year, hence why she has postponed her collection release until Monday.

Other celebrities taking part in the Black Friday boycott for Ferguson are hip-hop mogul Russell Simmons, Vampire Diaries star Kat Graham and Grey’s Anatomy actor Jesse Williams.
