OK now let's get to blackbonner's initial question. What kind of "stuff"?

Real world stuff.

A generic dress with round neckline and long sleeves, generic a-line with long sleeves and floor length. With morphs and good use of texture zones and textures that generic dress can serve as a base for many different styles. So even better if it's allowed as a merchant resource. 

Similar with catsuit-type set, with feet and gloves if possible. Likewise even better if it's allowed to be used as a merchant resource.

Shoes. Sporty (sneakers), everyday (loafers, flats), formal (like you'd wear with a tux or gown) ... and FLAT and HEEL poses to go with them.  Women typically don't stand on the balls of their feet very much when wearing flats.

Pants. Not too tight, not too baggy. Something in between that then can be morphed either way without too much texture distortion. 

Useful clothing is a lot like creating characters. Can you make a piece of clothing that can be morphed and textured to look like it's from another era or style? 

You get the idea.

Nothing "barely there". There's way too much saturation on that as it is. LOL
