Do I need The Most Happy AND Crown of Thistles?

While both seem to be similar The Most Happy is deeper, Crown of Thistles is a bright orchid purple. The Most Happy is still a bright purple, but more of a dark violet toned purple. I think they are visibly different polishes.

Colour: Red
Finish: Holographic
Opacity: Two Coats Shown
Brush Type? NEW BRUSH Flat, Wide, Rounded Cuticle

Anne Boleyn is very much a red polish whereas Rose Bower is a pink, so while they could be grouped as both being holographic and both being in the same colour family they are both very different. I think they are visibly different polishes.

Do I need Catherine Howard AND Whispering Waves?

They are similar in tone, both are turquoise and holographic. Catherine Howard is lighter and has more holographic partials than Whispering Waves does. The nail pop swatches are more colour accurate than the nail photo.
