OP, we’ve talked on one of your earlier threads about wigs, as I’m a long term wig-wearer because of alopecia - basically been bald since I was 19. So hello again :).
Your dress looks absolutely perfect, your figure is gorgeous. You don’t need in any way to cover it up/be more modest/be more sober etc etc. Although as others have said, it looks as if it’s going to be cold. I have been having a similar crisis about my DD’s graduation next week - I was beside myself at the weekend as I was told many of the mothers would wear hats (ffs hats+wig=disaster. Just not happening). Also because of a previous accident, the only thing I can ever wear on my feet are either clumpy fly boots or trainers. So I am going to be hatless and wearing a dress and trainer combo. A ‘friend’ made me feel really bad about that and I cried all over another thread about it. Then I realised that graduation is really about triumph - not only for the academic achievement, but also for us as parents, that we have steered our babies into adulthood and independence. I reckoned that was worth a celebration, trainers/bald/hatless, whatever. My daughter’s sage advice to me was ‘mum, just be happy, you always look great, and I don’t give a shit what anyone thinks’. So (I think I’m getting to the point!), go, celebrate and don’t worry about the rest. My own graduation was a very sad affair, for reasons I won’t go into, but nearly 40 years on, I still remember it as a miserable day. We have the choice to make our daughters’ day wonderful, so go for it :)
Re wigs, I always hack mine about, they take work to look natural and ‘not perfect’ which is always the give away. But actually, I don’t care what anyone thinks of my wigs. It’s not my fault I need them, I didn’t ask to be bald, and I change mine up all the time - my DH is always losing me in shops as he can’t remember what I looked like when I left the house. The important thing is that YOU are happy when you look in the mirror, and if you like your wig, wear it and enjoy. Have a wonderful day.
