Congrats! My suggestions are below - I've marked the "nice but unnecessary" items with a question mark, as I'm not sure how much you're looking to wear. I really recommend "Glow by JLo" as perfume - seriously, it's a clean, soapy but unobtrusive scent so it seems appropriate to me
.
Tinted moisturiser: No7 Triple Protection, for minimal coverage/ Foundation: Bourjois Healthy Mix, for fuller coverage. Applied with Real Techniques Expert Face Brush (extremely quick, great coverage and airbrush finish - a must-have if you're pressed for time, IMO).
Concealer(?): L'oreal Touche Magique, for under-eye circles and minimal blemishes OR Mac Studio Finish, for more noticeable blemishes (really long-lasting).
Powder: No7 Translucent, applied with any old brush (although Real Techniques does an excellent one if you're looking).
Mascara: No7 Expert Lash (lasts very well but isn't waterproof, so easy to remove at the end of the day).
Blush(?): If needed - No7 does some nice matte ones (Soft Damson and Candy Pink are very flattering), Bourjois also does pretty ones but they tend to be more shimmery. Any old brush will do (Boots own brand is nice).
Eyeshadow(?): Wheatsheaf by No7 is a good, slightly shimmery neutral that will wake your eyes up a bit but doesn't need careful application.
Lips: Carmex or similar lipbalm.
