maternity clothes for work

jfresh

I work in a professional environment ( at a bank) and I am used to dressing in structured clothes, espcially high waist pants with shirts tucked in. So at 14 weeks I am not exactly showing but I feel like I have a gut right now. I feel huge in the flowy tops but don't feel comfortable in the tight ones and many of my pants aren't working because of the fancy clasp on slacks I can't do the hair tie trick. I have looked at maternity stuff at places like target and old navy but there isn't much for professionals there. I am not too comfortable shopping online- I hate to pay return shipping if it doesn't fit right. Any ideas for places not too expensive for working moms to be? Or tricks for the inbetween flat(ish) tummy and bigger bump?
