Best alternative to oodie sleep tee

[Jbrown76]

Firstly, are the sleep tees worth £49 (on sale) and what is the next best cheaper equivalent?

I know on 5poundstuff you can or could get proper oodies (bought some), just wondering if there's any sleep tees either dupes or official but much cheaper.

I suggested to another person on here getting an oversized man's t-shirt, usually made from 100% cotton so washes and wears well.
They got theirs from Asda for a fiver!

I think she got a four XL

Thank you x
