A former landscaper here.
Forget the jumpsuit (full-suit).

A landscaper must be able to move freely (kneel/bend/squat).
A loose jacket with loose pants/jeans - the best combo.
All my jackets are $30 tops; not paying more; not necessary either.

PS: as a landscaper in winter, I don't mind a full-suit t then (VERY well insulated at that - a different priority in winter);
but winter and the bees don't overlap - a non-issue.

....... Jeans don't breath and can get hot and sweaty pretty quickly out in the blistering heat.

When you are in landscaping (just as in construction) - safety trumps the sweat.
Tough jeans are about safety of your legs, while still allowing the work.
Steal toed boots are hot too - but their safety trumps the flip-flops.

Of course some landscapers will show up in flip-flops and shorts - unwise to hire such folks.
What is wise - you dress properly and you start your work at 5am (and done by 2-3pm when the real heat strikes).
