Boy groups
Seventeen- Really cool dancing that sometimes the MVs don't show great so I'm linking the choreography videos too (I prefer them over the music videos)
Choreography Bit of intro you can skip through until the video starts
Choreography There's a bit of intro so the video doesn't start for like 20 seconds
BTS- Really popular known for really good dancing
Girl Groups-I don't know what you mean by them dressing up super suggestively. Except for a few groups that isn't that common. Especially showing of breasts is extremely uncommon. Do they were midriffs and skirts/shorts sometimes? Sure, but it's not really suggestive in that way.
Gfriend- Really hard and pretty cool choreography with lots of electric guitar and upbeat songs. They wear shorts/skirts, but it fits the outfits.
The choreography for Fingertip has its own MV version that's worth watching too
Pristin- New group with really fun choreography so I'll link those videos too. They have a lot of female fans so you might like them.
Adore U(cover of Seventeen's song from above) A few of them are wearing shorts and what not, but it really isn't suggestive. Also there isn't an Mv because it's a cover only the dance version
Wee Woo they're outfits obviously aren't something boys would wear but they're not that bothering and the choreography is cool especially in the last chorus I would watch the choreography version too even if you don't like the song just for the choreography
