Angelina , but with normal clothes and skirts i never had a problem to do gardening
OK, thanks. (Obviously) I have no experience wearing skirts (or kilts), and even little experience gardening (love my apartment!). But I assumed a tight skirt might hamper your movements in the garden, with a short skirt you might expose yourself when bending over, and with a long skirt you might step on the hem when you get up from crouching/sitting. But perhaps there are enough skirts not that tight, short or long, that will work fine.
And yes, of course you don't wear your Sunday best when doing house- or garden work. Bib skirts and pants are traditionally sturdy and informal, so they are a logical choice. Although there are also lots of ones available that are more dressy, and suitable for office work or going out. Never (yet) seen wedding overalls though 🤣
