If you have seen a navy blue t-shirt in your dream: It seems that it would be better not to share your ideas until some issues are clear. On the other hand, you should not forget that you have started to experience some difficulties because of your excess weight. To see a navy blue t-shirt in your dream refers to working hard, the power you will gain by working hard, a trouble-free life and enjoying life. Not wearing a dark blue t-shirt in a dream means being pessimistic about some issues and therefore delaying your plans and missing the opportunity.
