weekend fun with coworkers?

[jaamkie]

so... I've started flying to another city each week for work, and my team lead travels in as well. We get along quite well so far and spend a lot of time together working, at work happy hours, and not working- sharing cabs, eating together, sitting in the airport, etc. While I think we both have good friendly intentions, I wonder where to draw the line- I don't want to make innocent things awkward, but I don't want to accidentally annoy or embarass him either (like, we coordinate our hotels and flights so we can share a car- do I assume we'll drive/eat together or do I casually ask every time? would it be weird to suggest going to a movie some night as a reward for finishing our work? should I expect to always walk together in the airport or do we go our separate ways? how early/late can I call/text with non-urgent work thoughts/questions?).

In particular, he asked me along to spend an upcoming weekend together with another (male) teammate in a nearby city just for fun- would it be outrageously inappropriate or just funny office gossip to wear a corset cat-costume when going out saturday night on halloween? (I work in a mostly-male career so I'm used to being the one woman in a group of men; I don't mind being talked/joked/fantasized about or kindly turning down tentative advances, but I DO mind coworkers being offended or judging me negatively) And should it be strictly stay-out-of-each-other's room or is it ok if we natually end up together to continue a conversation/watch TV/etc? Oh, and should I graciously accept the guys' instinctive opened doors and help carrying things, or should I demand to be treated like one of the guys?
