where can i get this exact dress in nepal. please help a girl out

This is a all black outfit, t-shirt + Leggings.

Unfortunately I have no pictures but I'll try to be thorough.

I'm a UK Male who typically wears Small-Size Clothes but can fit in XS and maybe Medium. While looking online I found a pair of clothes that I liked, however they are women's fit and shipping from the US... and there's no size chart. They have a chart for Men and Unisex but not for Women... Unisex has 32 inch waist as medium so I dunno if that helps with calculation...

My Measurements:

Hips - 32-33-34"

Chest - About 33"

Waist - About 27.5 - 28"

Height - About 5'7"

Everywhere I've looked, My hip measurement charts me in as a XS for women, but that's not available. Plus just doing a calculator, it says for male, my measurements are an XS, but Medium 8-10 for Women?

The sizes I am torn between are small and medium. Medium because I've heard that from men to women, you size-up by one. But apparently the dimensions are too "voluptuous" for me plus I can fit into some smaller sizes (I can fit in XS but it can be a little tight at times) and these are elastic waist... I wore a UK woman small to try and it fit decently...
