Serge needs a mid-life crisis.

It's time, Serge. Long past time. You stand in a shadowy booth, wearing dark colors. Your arms and legs are like sticks. Your skin is pallid and your body is oddly bloated. Is it depression, Serge? Has the bottle got you?

Heroes are beginning to laugh at you when you suggest THEY need a makeover. Come on, honey, grab those bootstraps and heave!

I have a couple of ideas about this, so be still a moment and listen.

First of all you need to get into better condition. Some time in the gym will make you feel better, and your clothes will hang.

Secondly, you are far too conservative to be taken seriously as a fashion adviser. Don't be afraid to shine a bit, babe.

Third, keep it simply fabulous. You're a Winter, darling. White is definitely one of your colors. Come over here and stand under a light for once. Ooh! Look at you!

There now. Your superior glare has so much more power than it did. The Tsoo are out back in the alley, but they want to talk to you about new tattoo designs and better footwear.

Don't thank me, just drive it like you stole it.

This sounds like a Job for ARBITER FABULOUS!!!

I especially like the third one.

First one's my fave.

I'm glad you like some of them! I am wondering if there is some sort of rule that the tailors may use only free costume items for their outfits.

The first design is almost exclusively purchased or unlocked parts.

The second one has many as well but is closest to Serge's present look. It is slightly cheated: I had to add the shield-badge to his chest in postwork because the Steampunk cravat is in the same chest-detail slot.

The third design (the white/silver gray one) is completely free.

I'd just love to see Serge get a new look and better lighting.

If our only choices are the ones in the OP? I say we keep what we have in-game already.
