What are the best social channels to advertise my startup?

As of now, Instagram would be the standard choice especially for fashion brands to utilize as an advertisement platform 

Why Instagram? 

• As of October 2020, a total number of 1.2 billion unique visitors were active, according to SemRush 
• As of 2020, the potential audience reach for advertisers on Instagram is 1.16 billion 
• There are over 90 million people who tap on Instagram product tags each month in 2018
• The largest advertising audience on Instagram is around 25-34 years old, following up with those 19-24-year-old
• Brands can potentially reach out and collaborate with influencers of their choice, enabling further reach of their fashion brands 

According to global fashion search platform Lyst, Instagram remains a platform that could set trends and boost sales. 

One of the examples is with the Australian Brand Realisation Par where their long-sleeved Alexandra dress has flooded Instagram feeds where even Kylie Jenner and Bella Hadid had come across it. 

Following their success is their leopard print skirt which had been sold out numerous times online which even led to leopard print spin-offs. 

However...

Tiktok can be considered as an alternative as well 

• According to a poll, they have found that half of Instagram users aged between 16-64 also uses Tiktok 
• Last year, they had 1 billion active users, surpassing even Youtube 
• An ongoing trend with the #tiktokmademebuyit where people would share the products they bought on Tiktok
