It's an embarrassing question/recommendation for me to ask, but what kind of clothes will help me to look more my age and like a mom, but not take away from the fact that I am only 30?

I am a mother of 3 kids, I am 30 and I've always felt very young. I've always shopped the Victoria's Secret Pink clothes because I really do love that style..but I'm now realizing I'm too old to be wearing that outside of the house. My turning point was when I went to a parent/child event with a friend and her daughter and one of the hosts talked to my friend and gave her something she needed to hold on to for her child (she is 35 and dresses properly to look like a mom). The host looked at me and passed me up.. I finally got her attention and said I'm a mom, too...this is my daughter..and the lady apologized. But i understand why she passed me up. Here I was in a VS Pink zip up and leggings. I am also very short, which doesn't help. So I'm coming here for help i guess. What kind of clothes will help me to look more my age and like a mom, but not take away from the fact that I am only 30. I'm so embarrassed to even be asking. But what do you ladies recommend? Brands, ect. I know what works for one, doesn't work for all. Please help me? Lol. Thank you!
