Hate to admit it, but I shop at Plato's Closet (consignment store for upscale/trendy teen clothing).
I go for what flatters my figure and try to stay away from the 'super busy' stuff or outright girly/girly (e.g. ruffled mini-skirts, although I did wear them in my early 30s, for better or worse).
I like the low rise jeans in a boot cut or slight flare. My gf runs a Plato's and says the trick is that all shirts are longer (nothing short). I don't think empire waists flatter anyone but the pregnant (and maybe my 7 yo?) but that's just me. I like fitted shirts that go over the waist band of the jeans somewhat (so you don't flash).
Have fun & good for you hmom5!!
