Sculpts Kpop kind of dolls?

The four brands that may be a good fit for you with full dolls are Telesthesia doll's boys, Dollzone's 70cm selection, Luts' SSDF line, and Heydoll I have a 68cm boy that is a great poser. Individual heads I think Illusion Doll has some sculpts, Switch also has some too.

 

Xagadoll has some Dolls that are actually even styled like musicians on their promo photos, like Macula and Rohee.

Rohee, 60cm Xaga Doll Boy - BJD, BJD Doll, Ball Jointed Dolls - Alice's Collections
Macula, 60cm Xaga Doll Boy - BJD, BJD Doll, Ball Jointed Dolls - Alice's Collections

I think Ash and Lucas might fight the vibe too:

Lucas, 60cm Xaga Doll Boy - BJD, BJD Doll, Ball Jointed Dolls - Alice's Collections
Ash, 60cm Xaga Doll Boy - BJD, BJD Doll, Ball Jointed Dolls - Alice's Collections

 

I'd say Loong Soul if you order not a full set, because they are fantasy styled. Their sculpts are very k-pop beauty standard.
Ring Doll has a few guys that I think can be k-pop stars, like this one Yuvaan, 78cm Ring Doll Doll - BJD, BJD Doll, Ball Jointed Dolls - Alice's Collections too

 

Came in to say Xagadoll but someone beat me to it haha. But seriously check them out

 

( Just had Mountains on repeat for a while yesterday.)

Souldoll had some great sculpts for that, but it's unclear when/if they'll be available again. It seems there were some issues that stopped them being able to fill orders for a while.
Similarly, Migidoll's Style boys have been limited in their offerings lately, though some of the older sculpts you might find secondhand.
Also couldn't help but think of Withdoll's Jay, though the new body is a little taller than you want.

Not sure how helpful any of that was, but good luck!


Edit: More thoughts - BJD Gravity, maybe Dopple Maiden?

 

I feel like Dikadoll and Dollits give boy band vibes! They have the face for it for sure!

 

Came in for the K-pop title, ecstatic that you said Straykids! I agree with all the suggestions, but I know I’ve perused Alice’s collections and have seen many that would work from different brands! Always said in my head how they all looked K-pop bandish.
