That's a great skirt, very interesting. I can DEFINITELY see it working in a funky and non-"sweet" way. Kyle, would you post a picture of you in the skirt and/or describe your style and some potential tops to us? I think you're new to the forum, correct? (apologies if I missed you; I haven't been keeping up that welll lately...) It will totally help us give tips.
If I had that skirt, I'd try and pair with my sleeveless black cowl neck top or a v-neck top and red sandals. I imagine that a relatively simple top, either sleeveless or with snug sleeves, will make the skirt look less "sweet". I'd avoid puffy sleeves or a collar. For cooler temperatures, I'd pair it with a cropped denim jacket.
I can see other colors working with the skirt as well - depends on what you like and what's flattering on you. Maybe a fuchsia, kelly green, a mustardy yellow, rich red could work on top (but it's hard to figure out the exact shade of blue in a photo). And again, I'd keep the top simple and let the skirt do the talking.
It would be great to see the length on you. If it's below the knee, it probably is too long.
