As all the size info here is geared toward female-bodied people, my experience with Rosabloom sizes might be helpful. My size is
height = 1.85m,
bust = 97cm,
waist = 86 cm,
hip = 100 cm
I took the "L" size and it is a snug fit. Would not want it to be tighter, but I also know that after some time the fabric loosens a bit. So rather an L than an XL!

As I only recieved it today, I cannot comment on durability etc, but I also bought another jumpsuit in November 2018 and it is still looking spectacular (XL back then, so a bit too lose for my taste now, but noone looking at me would notice, it is more the shoulders falling off too easily - which would not be a proplem with the current jumpsuit, as it has no shoulders). I wore it very regularly to festivals and parties and it endured quite impressively - my favourite outfit... Even the butt-sequins held on, so there are no noticeable patches without sequins, while of course they are getting fewer, but since they are so abundant, noone notices. So I expect this jumpsuit to last at least as long :)

A nice detail, that I only realised when I held it in my hands was that the sequins between the legs are small as well: amazing!

Looking forward to many more years with this spectacular new outfit!

Since I already own some Aphrodite jumpsuits and Fifi leotards, I was really excited about the Iris jumpsuit because this is the perfect combination.
It‘s the best unisex jumpsuit Rosa could‘ve created and the Chameleon colour, which i bought, is simply stunning.
If you’re looking for the all over sequin experience that definitely will keep you the center of attention, look no further.

For a sequin jumpsuit you can’t get anything better then Rosa Bloom!

I got a size L (uk14-16) it’s a nice stretchy material and sequins are covering every inch!

Once it’s on it feels thick and warm but that just shows the quality of the outfit!

10/10 would recommend to everyone!
