I usually buy it abroad since I’m not based in the Philippines but its the first time there is a significant difference in the dimensions. Maybe from different supplier? I’ll observe for now maybe it will change with a few washes but since i cannot return it i guess I’m stuck with it.

Possibly the worst things I have ever bought from M&S and doesn't even warrant one star. I bought size 'L' . I always wash stuff as soon as I receive but after washing, they went to size XXL and all out of shape.
Exceptionally poor quality and just an apology when I complained when I should have at least received a voucher or anything for that matter.
My advice, don't waste your money.
