Next suit?

[mdg137]

Looking for some input-- I started about a year ago to completely revamp my wardrobe-- managed to do so really on the cheap. (Thanks SF and ebay)

I wear a suit 3 times per week on average, sometimes 5 times if I have to be in court everyday. I am in Michigan, so there are pretty substantial seasonal fluctuations.

So far, Ive cobbled together:

1. Dege Navy with subtle lighter blue windowpane single breasted two button.
2. RLPL Gray pinstripe 2 button single breasted
3. RLPL Blue pinstripe 2 button single breasted
4. Canali Navy DB
5. Canali Navy tone on tone 2 button single breasted
6. Gieves and Hawkes tan/celery colored tone on tone windowpane 1/2 lined two button SB
7. BB 1818 Madison glen plaid with tan overtone 3 button single breasted 3 piece
8. MTM navy 3 button single breasted 3 piece
9. HSM B/W houndstooth 2 button single breasted 3 piece (fairly heavy)
10. MTM Charcoal DB

Obviously, the quality varies a bit, but theyre pretty solid, or at least solid enough for me.
Amazingly enough, the total price (before tailoring) for these acquired over the last year, has been 2867.00 (I never paused to add it up before)

Im thinking about adding one more to the rotation, looking for the maximum versatility, but still with a bit of flair--what would you suggest?
