I'm a big fan of this aesthetic. If you appreciate the usability of W95 without needing a pixel perfect copy, it's very easy to theme KDE to strike a really good balance.<p>As your global theme, use 'Reactionary'. Set your application style to 'MS Windows 9x'. For your icons, use 'Memphis98'. For cursors, 'Hackneyed (scaleable)'. Your Plasma style, colours, and window decorations should all follow your global theme (Reactionary). I keep the default Noto fonts because I find them quite easy on the eyes, but this is easy to change if you yearn for classic fonts.<p>My task bar (bottom bar) is set to use full names and not combine apps; I also use the application menu that looks like W95, and I've got it set to use a little W95 Start icon for that touch of nostalgia. Otherwise it's all very minimalist.<p>I've used this set-up for years and it works really well for me. I find it very conducive to being productive - it's stable, unchanging, and respectful of my attention and focus. I also don't need to hack away at anything or worry about updates - KDE officially supports theming and handles all of this really seamlessly.
