For 5.5b dress you'll be the one to judge if it's worth investing. I'd say it is very cheap and affordable. Get one if you can before it's gone. As I already said before, I speculate that this dress will be around 10b'ish as an equilibrium price due to its rarity and OPness.
I am dumb with game mechanisms, so I cant really help much when people ask me if this dress is good for RGs, so I simply went to test it in Sky fortress to see the actual numbers/differences. I can tell that this armor outplays my +13 Abusive Dex3/Str by miles when it comes to Demon/Undead monsters. The downside is it is not slotted. This dress is for pure offensive ie if you have someone to tank for you mainly.
Abyss Dress in Sky Fortress
Abyss Dress in Endless Tower
With this armor, you will do ET easily even if you're an inexperienced noob like me.
