Think about the cut in most tops with that fashion flare. They’re typically made of light material. Perfect because you get over heated a lot and you’re not about that sweating like a pig life.
And off-the-shoulder tops are typically A-line and have an empire waist Cut meaning no pressure on your achy boobs that are preparing for breast feeding.
The only concern may be the naked shoulder thing if that’s a concern. Otherwise, don’t be shy about being trendy too and picking up an off-the-shoulder too or dress soon!
