Hi Alyssak,
Without being rude thought I'd give some advice. I purchased a 3.5mm Eve wetsuit for my partner Carly who predominately dives in Vic's warmer months. 6mths later I then purchased 3.5mm vest for her to wear underneath her wettie. 8mths later I am now getting "5mm" Eve wetsuit custom made which I should have done from the start
One of the other girl divers in our club also uses 5mm. Don't listen to what blokes use!!!
You will get to spend more time in the water and that's what it's about
As for a mask go into a store and find one that fits "your face".
As for spare gear I will ask if she wants to sell anything.
