Honestly, I think DD looks really cute in her glasses, and she is happy day to day, but she wants contacts for the prom. She has also been told she needs to take her glasses off for her drama performances as they hide her face, so contacts needed for those too, as she can't see at all without them.
Fortunately DD not interested in having hair or makeup etc done, so there's a saving, and she won't have a tan done, as she is naturally whiter than white, so will be going for the English rose look, or in her own words, the slightly dead look !!
