Big W's matching mum and bub pyjamas flying off shelves

Mums and their bubs have fallen head over heels (and down the rabbit hole, if you don't mind the pun) for Big W's Disney-themed Alice in Wonderland pyjamas which come in both grown-ups and kids sizes.

Perfect for mini-me moments, both sets include a long sleeve top and matching pants printed with titular character Alice on a blue background.

The women's option comes in sizes 8 to 20 and costs $30, while the girls' option is priced at $18 and comes in sizes 2 to 8. Both sets are made from a polyester/cotton blend and feature the word 'Dreamer' in sparkly font on the top.

Going by the excitement on social media, the adorable sleepwear might not be on Big W's shelves for long.

"They are so cute!," one fan gushed on Facebook.

"I love these sooo much I had to get them for me and my baby girl also," added another.

One mum, Brooke from Queensland, even shared a sweet snap of herself and her daughter sporting the "comfy and pretty" matching PJs.

As did mum Kasey, who was ready for some Disney dreams with her 'mini-me'.

If something festive is more your flavour, Best & Less has the perfect mini-me buy: a novelty Easter dressing gown — complete with bunny ears on the hood, of course.

It comes in girls' sizes 3-6 ($20) and 7-16 ($22) and women's 8-16 and 18-26 (both $28 each). There's one for the boys as well, in sizes 3-6 ($20) and 7-16 ($22).

Hoppy Easter!
