I don’t see any reason it couldn’t be.
You could try something like this.
I really wish I could just say “Go to Disney World!” because I walk by the stand that paints parasols almost every day and I’m planning to buy unpainted ones for Lolita and they’re inexpensive and would be just perfect.
Anyway, something I would suggest is looking for wedding parasols. You have to do a lot of sifting to get away from the paper ones and the low quality lace ones, but eventually you find nice solid ones. Usually it works better if you search for wedding umbrellas rather than parasols so you can avoid things like that. I’ve actually even found some cute ones searching “ruffle umbrella” on ebay. Once again you have to sift through junk but sometimes you find a gem. Also look at childrens parasols like the cute ones Bella Umbrella carries. They’re a bit shorter but they don’t look too weird being carried by adults.
They do through their shop on Rakuten Global.
A friend of mine had the same problem with hers in similar conditions.
I think in cases like that it’s probably okay to use them in a light drizzle, but not heavy rain. The biggest problem I’ve heard of with their parasols is that they rust so just be sure to take care of it and if you do use it in the rain dry it with a towel before putting it away.
Some are and some aren’t. It looks like all the ones they have in stock right now are. It will say specifically on the page “For rainy and sunny” if they are.
A fair number of brands that make parasols have them waterproofed so they can work in rain. Not all of them of course, but if they’re waterproof it’ll usually say on the item page. My Innocent World parasol is waterproof and I’ve been using it for a year with no problems. I know that most of Lumiebre’s parasols are waterproof too. Keep in mind though that when ordering a parasol online you’re taking a risk that it may be hurt during shipping. That’s the reason Bodyline doesn’t sell them overseas anymore and it’s why umbrellas like this are great because they fold down small so they’re easier to ship and harder to damage in the process. That isn’t to say that you shouldn’t buy a full sized one if you find one you like, but keep in mind that there is sometimes a risk of damage.
