The new moon in Leo this month on the 28th of July is especially exuberant as the Sun and Moon at 5 degrees Leo are both trine a stationary Jupiter in Aries, also a fire sign. So don't go wild. Just go a little wild. Buying little luxuries is fine, but buying clothes with Moon in Leo can mean you end up with something overly theatrical that you will never wear. And you will likely spend more than you intended.
The other planetary happening that makes this new moon memorable is the approaching conjunction of Mars to Uranus and the North Node at 18 Taurus. Whatever house this conjunction falls in in your chart, do beware. If you have your birth time you can obtain a free copy of your chart at astro.com. If Mars Uranus is making a helpful aspect to one of your planets, for example the Sun, then it will move things forward in a good way.
While you can rely on the Moon in Leo to be fun (and yes a great time to have a party-go all out) it is harder to predict what will happen with Mars and Uranus together. Last time they were together was the Biden inauguration chart, and it has not exactly been a smooth ride for the U.S. over the last 18 months.
Since Mars and Uranus are both in Taurus it could have to do with money, or the earth. The astrologers are not predicting what, they are just predicting when. The dates to stay calm are July 31 and August 1. It is one of those aspects where you really don't know what to expect, except that it will be unexpected.
While Rachel Brosnahan is a Cancer, she does have a Leo midheaven and it does help her channel Mrs. Maisel. Those clothes! So perfectly Leo, in the best sense of the sign.
