Thoughts on those definitely-not-girdle holsters for everyday CC?

I want to carry some kind of micro-compact (TBD) on me and I would like for it to be well concealed without having to think too hard about my wardrobe. (it's too hot to wear more than a t-shirt for the better part of the year in my country)
From what I can tell the "default" option for in-waistband is a rigid belt and a holster that goes inside the pants, which means only pants that can fit a belt and no tucking my shirt in.
Those gun girdles look like a good option on first glance but I would also imagine they get pretty uncomfortable on hot, sweaty days.
Would probably smell the part in no time at all.

Doesn't seem to be available around me and it's fucking expensive even without taking into account shipping, import taxes and (from what I heard) that buckle upgrade which is supposed to actually make it good.

The context is that I got my loicense and am now thinking about particulars
