Congrats on the weightloss DB!
Checked out MUJI today, quite a few summer basics: OCBD's, Linen, shorts, polos. What I checeked out seemed to be rather good I picked up a polo for myself and the cotton seems rather 'thick' and 'sturdy' (as polos come), the collar especially is quite sturdy. The polos came in simple colours (white, navy etc.) as did the shirts (blue, white; also a green I liked a lot). There was also a 90 dollar linen SC/Blazer, seemed nice though didn't get a good look at it, probably somewhat similar to the UNIQLO one SF seems to like a lot.
I despise cricket....sorry DB, TBM etc.
