When you see a great cosplay, there are many surface level thing that stand out as to why the cosplay looks amazing. Things like garment construction, prop craftsmanship, and attention to detail, etc...
But one important aspect I don't see discussed very often is proper undergarments. As is true with a lot of period clothing, a lot of cosplays either depend upon or could be improved by using specific garments to shape the body to the costume.
Things like shape wear, corsets, dance tights, even lingerie tape, etc... can add a whole other level of quality to your cosplay that most people probably won't even know to point out or compliment you on.
So let's discuss!
What kind of special undergarments have you used for cosplay?
Best brands/retailers for various products?
What are some cosplays that definitely would require special undergarments to achieve 10/10?
For myself, one thing I do is wear a special bra for larger breasted characters. I'm about a b cup and I have a bra that can pad me out to a DD, works really well for those busty anime girls.
