Halloween can be rough during the first and last trimesters of pregnancy: Either you're fighting off candy-induced queasiness or struggling to schlep your pumpkin-sized bump around. But if October 31st happens to occur in the magical middle of your pregnancy, odds are you'll feel up to enjoying the holiday... and these Halloween costume ideas for the 2nd trimester will definitely come in handy.
The options are pretty much endless during this phase of being preggers. If Halloween happened in another few months, you might find that your only choice is to paint your belly like a jack-o-lantern, but right now you're just pregnant enough. A visible bump means you can choose to use it as part of your costume; at the same time, if you don't want your disguise to highlight your pregnancy, you'll still probably be small enough to hide it (especially if you're in the early 2nd trimester).
Whether you're feeling super low-key (as in, "all I can handle is a graphic tee" low-key) or ambitious enough to dress up like an actual character other than yourself, you'll find something on this list that works. And some of them can even be worn again, on non-pregnant Halloweens to come (unless you plan on timing all your pregnancies to coincide with Halloween, which, why not?).
