I'm also a female, a designer (ux/ui) and I try to spend as little time as possible thinking about my clothing and hair, while still looking like a designer.

The look described here sounds simple, but super casual and perhaps a bit dumpy for a designer. I find that the easiest thing for me is to wear all black clothing that fits well (don't buy it unless you feel great in that shape and material, no compromises). Avoid cotton because it fades and has a gross texture. Done.
