Most of the latest lingerie collections are very girly, so grab the chance to indulge in florals and lace - even if you're wearing monochrome black over the top.
Some sets are so cute it seems a pity to cover them up.
But it's hard to feel pretty, let alone sexy, if your underwear doesn't fit right. This is one instance where you don't want your cups running over and you definitely don't want bulges around your bra line.
Most specialist lingerie shops - and many department stores - offer free fitting services, so get measured regularly to ensure you are wearing the right size. You will be surprised at what a difference it makes. One woman I know said having the right bra size even improved her posture.
I know it can be hard to justify spending a lot of money on something no one will see but good-quality lingerie lasts a long time, especially if you take care of it properly. And knowing that you're wearing lovely underwear will give you a confidence boost that could prove invaluable.
