Hair and make up trial

I personally wouldn't skip the trails. Trails are meant for you to see what you like and don't like. If you have never dealt with your hair and makeup artists before you really should take the trail. That way you can tell her your envision right away and see how it looks on you rather then the day of your wedding. You may not like what you originally thought and might have to change a few details here and there

Hello Desiree,
As makeup and hair is important for us brides. I would say to make sure that you’re able to get your trials done to confirm your ideas are met.

Wishing you all the best in your wedding planning and decisions.

Hair and make up will be important to you to make your overall look to match your style and dress/accessories. Don't skip this part since you will want to know your in good hands of a professional to give you the best look.

Depends how confident you are with the MUA and hair stylist you chose. I definitely recommend a trial as it gives you a chance to see what you can expect from your artists the day of. And if you do the trial then you can request any changes or tweaks you'd like for the day of. For me, I'm really glad I did the trial because my artist applied something under my eyes (can't remember what since I'm not a makeup person haha) and it made any wrinkles I had really visible close up. So I asked her not to apply it for my wedding day and it made me much happier with the look overall.

I wouldn't skip the trial unless you've had prior experience with the people doing your hair/makeup. Obviously if you can't do a trial because of restrictions that's different and you need to do whatever is safest (I'm not sure what restrictions are like right now in Ontario), but it's still a risk to skip it.

I would consider doing it yourself or having a friend/family member do it for you and do trial runs yourself at home. At the very least if you skip the trial and just wing it on the wedding day give yourself lots of extra time to redo anything you don't like. I'd factor in an extra 1-2 hours of buffer time just in case you hate your hair or makeup and have to start from scratch.
