How long should I wait to SE Zalando again? It’s been 7 weeks , and I’m planning to do a £1000 zalando DNA . Please let me know. Same address and account .

7 weeks Is ample time to perform another SE.

Did the previous one Involve the DNA?

Yes it did

To help minimize suspicion on the account, It's good practice to change methods between consecutive SEs, particularly those that Involve high value Items.

Personally, I'd choose another method but In your case, the time of your last SE works to your advantage so this will make the DNA appear as a legit claim.
