We love all the O2 items we've purchased so far. My teenage daughter wears XS. I wear M. No doubt we'll be ordering more colours in Spring!
I now own six different colours in the scoop bamboo tops as they are so divine to wear, never smell even after playing pickleball or a gym session, perfect as the only top or an underlayer. Cannot recommend these highly enough!! Thank you O2.
These long sleeve tops are lovely,warm and soft
