TL;DR manga is very funny but not too great in the plot department. Read if you love genderbender comedies and don't mind about unsatisfying ending.
I know comedy is subjective but if you love genderbender comedies such as Prunus Girl, Himegoto, stuff from the now defunct Waai! magazine, etc, then this is easily one of the funniest out there.
This manga was made before these genderbender stories went on some kind of "oh it's exploring deep issues and whatnot ala Hourou Musuko" revolution (circa 2016-now) so if you're looking for that then sorry, you won't find it here. You go into this if you just want to laugh and have a good time.
First and foremost this manga heavily leans toward comedy and it set up jokes or funny situations really well, but it suffers on the plot aspect (even if there seems to be hints at more story later on, it doesn't pay them off). There are some downtime to reflect on some genuinely wholesome moments, but they are usually just there to make you empathize with the characters or it's another setup for a punchline in the next chapter. The main characters, Ochi and Izumi, have a nice dynamic and as the main pillar of the whole manga they're doing a good job.
Now to address the elephant in the room, the ending is not great. It seems more like a sequel bait than an actual ending and pulled off the infamous "we've gone full circle and got back to where we start off" card from slice of life manga. I honestly think this manga would've benefitted from a longer serialization (or an actual sequel), if it was longer it could have easily pay off some plot details that are hinted at throughout the manga and could even be elevated to something great (like an 8 or 9 out of 10).
Of course, that didn't happened so if you don't mind about that aspect then feel free to pick up Boy Skirt for your dose of genuinely great genderbender comedy (I'm legit dying from laughter reading this if you're still not convinced).
