I have made two big orders recently for full price items: vest\tank tops with built-in support, and one of their pull-on bras.
I have tried to make returns - well within the period - for the sizes that don't fit. Although the website page for each of these items says that they can be returned within 28 days, when I try to use the returns portal (Uniqlo no longer include returns notes in the parcel) I am being told that the items are 'final sale' and cannot be returned.
It SEEMS to be because these are items classed by Uniqlo as underwear, which Consumer Contracts Regulations say need not be refunded. No answer as yet from Uniqlo.
I can't help thinking that this was intended to cover knickers, not crop tops and the like. And as I said, the website pages for them specifically say they CAN be refunded.
However, since I am £60 out of pocket unless Uniqlo change their mind, I thought I'd warn you ...
