When is it OK to copy another business? Please help

[candlebusinessidea]

I’d like to start making candles and make a business out of it hopefully , I’ve done some research and watched YouTube videos of how to make candles, there’s a few candle businesses on social media I like. I love their concept, one makes candles based on your memories.

AIBU to copy this concept? But everything else will be different, packaging, labels, candle holders etc?

I’m sitting here thinking, there are so many businesses doing the same thing. When is it OK to copy and when is it not? For example, Uber have competitors like Lyft ( America) Bolt etc, all offering the same thing.

What do you think? I don’t want to be accused of copying, but where is the line?

Be careful about staring a "cupcakes and bunting" business. These things go in trends and I have seen a lot of handmade candle business in the last couple of years.

I know someone who gave up a very lucrative career in the city and started up a handmade soap type business. Imagine a Gwyneth Paltrow Gloop type thing but before GP went into it. She invested all of her (considerable) savings into it. She had outworkers, networked like crazy (Peter Jones was bigging her up all over twitter) and it failed. She lost everything. I think she thought she would be the next Lush but with better morals, unfortunately she just couldnt make enough for it to be profitable.

As a paying hobby it may make a bit but I wouldnt bank on it being a full time lucrattive concern.
