Intimately FP Spring Fever Shortie Briefs

I normally wear a size 10 in pants but ordered a large in these underwear. The size guide says large is for size 12-14, but they are very tight, uncomfortable, unflattering, and I am building out of them. There is very minimal stretch. Maybe an XL would have fit, but I’m still not sure if they would be comfortable just because of how stiff they are. I’m glad I didn’t order multiple colors like I originally planned to do.
