Hello Kachie, thank you so much for leaving a comment on my article. Glad to hear that this is helpful for you.
I was also transitioning my career to UX/UI designer from fashion industries and this kind of whole process of case study was very helpful for me to teach myself a lot. Hope you also learn much from your own case study :)!
Have a great day and wish you all the best for becoming an UX designer.
P.S. I’ve been also writing new case study for redesigning responsive web so hope I can show you soon ;).
