I like to wear comfy clothes, but I still try to not look like I'm wearing homewear. Please look at my avatar and tell me what you think. Ignore the smudge on the mirror. Please be honest, but in a nice way. I need your constructive criticism.
I agree with another commenter that it actually would help to see your face, because that matters too. But I get it.
Overall it looks comfy and fine. It does look a little mom-ish. I don't think the colors in that particular outfit are the best together but that's my opinion. What if you did that outfit with a shorter cardigan over, or changed out the button-up shirt for a v-neck t-shirt? If you add a necklace or a cute scarf that could make the outfit more fun and younger, too.
I like the pantyhose and skirt a lot. The top doesn't really work because it does not fit with the rest of the outfit because of the pattern. If it was just plain purple it would work. A different cardigan too, this one has too much of a bath robe look to me. Still much more effort then most girls at my college seem to put in.
You look fine to me but appearances are goal driven. What exactly do you want? You could look more professional if that's what you need, you could encapsulate your shape if you want sexual responses and attention, and you could change ever so slightly if you wanted more of a look conducive to a specific appeal.
Overall, you're fine though. Decent and acceptable insofar as being outside goes.
I think you could easily make this outfit much nicer with some nice accessories. As it is now, it's quite plain and a little unflattering. Maybe try some cute ankle boots and a statement necklace? If the cardigan was a little less long (ends around your hips) that would be even better because your figure wouldn't be completely lost in it. Hope that helps!
