"So you've just returned from a shopping spree at Consignment Cat, arms full of 'new-to-you' treasures. Your husband raises an eyebrow and asks, 'More new clothes?' Here's your chance to shine with clever wordplay:
'Darling, I didn't buy anything new today! I simply adopted some pre-loved fashion orphans. It's not shopping, it's rescue work! I'm basically a superhero for sustainable style.'
Then dramatically pose in your thrifted cape (because surely you found one, right?).
Remember folks, the real superpower is open communication in relationships. No need for secret identities here - your partner probably already knows your kryptonite is a good bargain!"
