I own many t-shirt bras and they're comfy and the fit is good. But I have a problem with my boob's moving when I walk. I'm a fast walker so I feel my boob's jiggle with me and I can see people looking at my chest and it makes me feel uncomfortable . I have to wear a uniform for work it consists of a polyester top and i wear a light jacket on top to hide what I can hide. I bought a light sleevless t-shirt to wear underneath the top that's two sizes smaller hoping it would reduce the movement but it's doing nothing. Please give me tips on what to do. Wearing a sports bra to work is out of the picture. It gives me a uniboob and with the many layers I wear. It gets suffocating. I live in a Muslim country and it's quiet conservative in hear, that's why I don't want my boob's to be very noticeable. Thanks.
