My boyfriend insists I look "effing hot" in this outfit, but I can't shake the feeling that it's just too small for me to keep wearing out. While I appreciate his enthusiasm and love that he finds me attractive, I’m starting to feel a bit uncomfortable in it. It's great to have support from him, but I think it’s time to be realistic about what works for my body. Fashion should make me feel confident and free, not restricted or self-conscious!
