Tips to hide a pregnancy, well after getting the bump?

I'm not crazy, I promise. We're expecting our second baby, but after a miscarriage that happened right after we announced (we had reached what we thought was the safe zone of the second trimester), and then since we've been struggling financially and family members are constantly on us about it. SOOO its been decided that we want to keep the pregnancy a huge secret until much further along, 6-7 months along would be best. If anyone might have some tips to hiding it for that long, please let me know because so far I've only figured baggy shirts into the equation😂
