I was over the petite dept at Dillards the first year after I retired from teaching. One thing that impressed me about the store was that while most store's "house" brands are done with lesser quality, Dillards doesn't do that.
Investments is geared to the basics a woman needs in her work life. It is good enough for secretaries, teachers who need something that won't upset them if they should ruin them. I wore them on the floor and they were good sellers. I must have bought ten pair! The ones I liked were poly/span., (not knit) called Fifth Ave. They have a zipper. They quit making them for a while and no one would hardly buy the pull up style. They had to bring them back.
For the use you describe, I would think it would be fine.
My favorite lines were Antonio Melani, which was beautiful fashion forward suits and beautiful work shirts with a type of polished cotton. Gianni Bini, is the dress and casual dress for teens. At 5' 6" I can wear the larges. I love the tops in this brand. Those are their highest quality house brands and well worth the money.
I had to quit because I developed sciatic nerve problems because I carried such heavy clothes. I'm much better now, thank goodness.
