Eparty so soon!!

My eparty is in 13 days (and im getting soo excited!!)
It's in my FIL's backyard..its very casual, i mean we're probably gonna have beer pong...
I'll be the only one really dressed up (and thats ok cause im the bride haha) but for after everyone comes and when i get sick of wearing a dress..i was thinkin of getting one of the 'Soon to Be' hoodies..or even making myself one of those Bride tanks..any opinions??

Also, do you think I should make the same tanks for my BMs, as a nice gesture..i mean it will probably cost me under $20 (only 2 girls)
