I've gained a lot of weight and I don't know what to wear...

January last year I gave birth via c-section to my second daughter, after a pregnancy with hyperemesis that made me lose 15 kilos. From that moment I started eating a lot and have gained a lot of weight, and these three last months of lockdown in my country have made it much worse...

I need to buy clothes for work, as the ones I have from previous years are too small, but I don't know what kind of clothes would look good on me now. I'm tall, wiht very wide hips and big breasts, and specially a belly that makes me look pregnant (my 4yo daughter has told many Times that I seem to have a baby on my tummy XD).

I've searched the internet but all the articles I find on this topic show pictures of thin women with the dresses, how is that supposed to help?

So, what kind of clothes would look good on a body like the one I described? I live in a very hot country and work in a bank.

Thank you in advance to whoever may reply! :)
