Suit collection for men

You're looking in the wrong places.
2 things to try.
Loads of big, very professional shops (most seem to be Indians - no idea why that should be).
These tend to have a very nice line in made to measure suits, mostly very expensive but very high quality.
There are also smaller, but still good quality places around.
I noticed on in the technology area of ITC Mangga dua a few weeks ago.
The shop was small, but his stuff looked very nice, and available in a wide variety of materials and colours.
I've been wanting a new black tie, so this has been of interest to me.

Added - a place called Pronto (I hope I'm right with that) does top quality suits (and ladies wear).
I believe they have several branches in and around Jakarta.
Not cheap, but the quality looks great.

you can go to "tanah abang", there's a lot suit collection
