I in some way was unfortunate that my mum packed a lot of my clothes for me so I totally over packed even though I told her repeatedly that I didn't need half of what I was taking.
I took and used... my travel clothes - pants and a t-shirt with sneakers. Which I wore for the first two days, then once I was at the hospital I wore what they gave me for the whole time I was there until the last day when I left to go back to the hotel, so I packed a singlet and a skirt (I still had the catheter in so the skirt was a must).
Once I was back at the hotel it was between two skirts and just singlets and flip flops, I slept in underwear and a singlet (from that day) until the catheter was out and I switched to 3/4 capri pants and singlets or t-shirts. It was surprisingly cold in the hotel restaurant for me at night so I'd recommend a cardigan or something more than a singlet that you can easily take on and off as needed.
My mum took coat hangers and bought some clothes washing liquid and washed underwear and singlets in the bathroom sink every few days as needed, this was a huge help even though the clinic provide laundering services, doing it yourself is quicker, cheaper and easy. Level three of the hotel also has a balcony that no one uses so if it's not raining you can put singlets and shirts on the backs of chairs and they dry in just a few hours!
I rotated between about 5-10 tops/singlets and two 3/4 capri pants, two skirts, one full length cargo pants and about 5-10 pairs of underwear,..... boy leg...

Two pairs of shoes ..(closed shoes) sneakers for travel and as flip flops were more than enough for everywhere between the hotel/clinic and shops! I just took them!
my only regret in this area was not packing a warm cardigan or light zip open jacket as the aircon there they have it super high/extra cold and with lack of hormones you feel that cold a lot more, mostly in the hotel restaurant, vans and clinic...well I sure did!!!! hotel rooms have air con that most people complain about but there is a spot between around 24-26 on the dial where it changes from cold to hot, once you find that sweet spot its fine!!!
