Ah, remember the best mermaid leggings? Yep, the throwback fashion statement is making a comeback once again. Can you really blame us for reliving our mermaidcore dreams after the release of The Little Mermaid earlier this year? If you're in need of ideas for your next costume party or just a pair of the best leggings to lounge around the house in, mermaid print leggings are the right fit for all occasions.

Ideal for Halloween if you're paying homage to Ariel or just as a fun pair of pyjama bottoms to throw on for your next movie night. If you're a fan of leggings with a print, then these are definitely for you. Usually decorated with a scale pattern, metallic effect and the colours of the ocean, they're a whimsical take on your standard (SEE: boring) pair of leggings.

Listen, we know it's all about honeycomb leggings right now, but believe us when we say mermaid leggings are back. If you want a new standout pair to wear to your yoga class then these are your gals. We'll forever remember them being paired with a slouchy knit, chunky boots and a hat for added effect (it was the Tumblr era, ok?) but now we're embracing them as part of our gym - and lounge - wear, for the foreseeable.
