1. We know you're probably sick of hearing it, but getting fitted is as important as everyone says.
Your boobs change size regularly, and the correct bra will give you support and make those assets look *~incredible~*.
2. There's no reason to be nervous.
Bra fitters are professionals that do fittings every day and totally understand that all boobs are different. Plus, you don't even have to take your bra off, so no nudity required.
3. A fitting isn't just a measurement.
We start by measuring your size, but every bra fits differently, so it's important to try lots of styles on to find a correctly fitting one. So don't just get measured and then buy a bra in that size—it might not be the right one for you.
4. You don't have to remove your bra to get fitted, but it's fine if you do.
Technically you don't have to remove your bra, but if you just want to be free then that's cool.
5. Your bra should be snug around the back.
But it shouldn't becutting you in two. You need the support, but if you're feeling uncomfortable, chances are you should be paying us a visit.
6. Some cheap bras are great, but some are also terrible.
Be prepared to pay a little bit more to get the lift you deserve. But know that your bra fitter would never pick an expensive bra just to get you to spend more—we want to find the best style for you.
7. STOP machine-washing your bras.
Washing machines are often the reason why your underwire is falling out. Spend a little time hand-washing your bras and they'll last longer (and stay white—no one likes a grey strap).
8. Losing or gaining weight means you need to be fitted again.
Those old bras just won't cut it any more.
9. Trust us.
You may have been wearing a 34B since you were sixteen, but that doesn't mean you should be.
10. Most women wear at least a back size too big, because it's comfortable.
But it's comfortable because it isn't doing anything—i.e. no support. If your bra rises up your back, it's far too big.
11. We'll say goodbye in six months.
When your boobs could be a whole new size. Remember that!
