Although they wont fix a blurry problem like your picture. But details can be enhanced by bump and specular maps. I no longer bother and my textures are none the worse for it. png then when I was sure it worked converted them to. dds files I never ever edited them because the quality loss was unacceptable, hours of work could be undone with one edit. I don't make clothes but 10 mb sounds horrendously huge to me for a texture, I could be an innocent in this respect as I said I don't make clothes but I do make very detailed wallpaper and the textures for that can climb unless I keep a watch on them. I have had it myself, if its very bad I leave it a couple of days and on return it nearly always is fixed or at least acceptable. I'm sure I read that here a long while back when someone else was having the degraded texture problem.
I could be wrong but I think S4S converts all textures to dds on import. Starfield mods have racked up an impressive 14 million downloads since the game launched 2 weeks ago and were super excited to see all the mods being shared. Ive looked around a fair bit myself, and havent found anything besides this, a purple UI recolor, and another gray recolor that hasnt been released yet. Unfortunately, I dont think any of those exist. I'm guessing it's done to reduce game lag. Thanks, but Im looking for a little more than a color change.
