Embarrassment, naturally.

In a single instant, Captain Carter’s toned physique was on display for all to see. “Eep!”

Peggy tried to cover herself with her shield, initially flip flopping between hiding her breasts and her crotch, before crouching down behind the shield itself - inadvertently exposing her buttocks in the process. The famous defender of liberty and fearless leader was now reduced to meekly hiding behind her Union J shield. Wanda chuckled, and then turned her attention to battling Captain Marvel.

But a quick glance at Wanda, the woman who had killed her allies in the illuminati and had opted to humiliate her in such a sadistic manner, filled Peggy up with blind fury, not just towards Wanda, but towards herself.

How could she give into embarrassment and cower away in shame? How could she let her fellow hero fight Wanda alone? How could she let Wanda win?

Captain Carter willed herself back onto her feet and readied her shield. She drew her arms back, and with a mighty throw, she sent her Shield - and her only source of modesty - hurtling towards the witch.
