I was wondering how you were getting on in Oz time, lovely to 'see' you again. You somehow suddenly look very Australian in that picture. Skint in Australia sounds like a bummer though, I can recommend depop as I frequently find cheap things on there but then it turns out they're in Australia and it would cost more to ship than to buy the item, seems to be a very popular app there.
I was thinking that about Muji pjs too, my mother had some and she was 10cm shorter than me and they were pretty much a perfect length on her. Men's may be a bit longer?
I'm going to pass on glittery trousers, I did see a very impressive metallic brocade pair of trousers with a peacock feathers pattern that were embellished with sequins from Dries van Noten in Paris. Very impressive but I can't get away with busy bottoms in heavy fabrics.
WRT compliments, IME people that know you compliment boring shit that rarely warrants a compliment but fits in their comfort zone and are less ooh and ah over more out there items, unless it's really out there and there's occasion for it. Randoms on the street are the opposite. Lot of that, I suspect, is cultural though.
