Mayonnaise: I always use real mayonnaise like Hellmans, but you could substitute with Greek yogurt for a lighter version, although the taste wont be the same and the dressing might be a bit thinner
If you DO want something saltier (say to drizzle over watermelon) you could try Greek feta or Isaraeli feta, which are often made with sheeps milk and are much saltier (and also so perfect for watermelon and mint salad)
To make a homemade ranch dip: Follow the exact directions above, but omit the lemon juice and milk
The half-placket can be buttoned up for a more tailored look or down so it's more laid back
Comfort allows you to enjoy the day rather than constantly adjusting your dress
