So I'm in the planning phase of making my own custom spartan from Halo Reach but I've haven't been able to figure out what to wear under it. I've heard a Lycra dive/swim suit is a good option but after a quick browse most seemed a bit pricey and I feel like they might be too stuffy after wearing it long enough. So I thought I'd ask you lovely people and wanted to know if anyone had any relatively cheap and/or less warm and stuffy options that they use or have tried! If it helps I will be making the costume out of foam.
