Like many women, I’ve long dreamed of a bigger bust. As a modest 34B I’ve experimented with every push-up, plunge and balcony bra there is, so I’m intrigued to learn of a new £150 bra that claims to take you from a B-cup to a DD in an instant. The Scandfit Try Size — dubbed ‘the boob-job bra’ — was developed to help women about to go under the knife decide what size implants to have. Not surprisingly, it has gained a following among women like me who would never have surgery but love the idea of trying out a dream decolletage for a day. Scroll down for video . At a size 34B, Annabel Cole (pictured without the bra)  has long dreamed of having a bigger bust but would never have surgery, so she decided to put 'the boob-job bra' through its paces . I decided to put the design through its paces in three variations — a C cup, D cup and whopping DD! Starting with the smallest first, this is what I found . . . FROM B-CUP TO C-CUP, BUT IT'S TOO SAGGY . Cleavage you can change like your clothes? Yes, please! I’m terribly excited by the idea of the Try Size — even more so when it arrives packaged in a white leather box. Soft, black and lace-trimmed, it comes with four pairs of inserts labelled one to four, according to their size. The inserts are measured in cubic centimetres, like surgical implants. The lightest, size one, weighs in at 50cc, followed by size two at 100cc, size three at 200cc and size four at 300cc. One added cup size is roughly equivalent to 200cc, and the idea is that the inserts can be layered in various combinations to create different sizes of cleavage. The Scandfit Try Size (pictured) has been dubbed ‘the boob-job bra’ and comes with four pairs of inserts which can be layered to create different sizes of cleavage . While the Try Size is pretty, it is also hefty. Out of curiosity I plonk it on my kitchen scales: the whole package weighs well over a kilo. I had assumed that the inserts would be silicone, but these are filled with rice and resemble silky bean bags. Apparently, rice is about the same weight by volume as surgical implants and can be moulded more realistically to your breast shape. Each bra cup has an internal pocket to hold the inserts. Annabel is seen here wearing the size three 200cc insert which takes her modest B cup to a C cup, she says she was sorely disappointed with the results of the rice filled insert on this occasion . I start cautiously with the size three 200cc insert, taking my modest B cup to a comelier C. The inserts prove easy to put in but the first hurdle comes with doing up the bra. Unlike those I usually wear, this has four rows of hooks — presumably to cope with the maximum potential weight — and it takes me a few extra minutes to get them fully done up. Once the bra is on, I feel let down. I’d been expecting some kind of ‘Hello Boys’ perky bosom but I’m sorely disappointed. What I get is more like a real-life middle-aged C cup — ever so slightly droopy and a little lopsided. But I persist and push around the rice, patting and smoothing until it creates a soft, rounded shape. I decide to try out my new look on my harshest critics — my children. I throw on a tight T-shirt and wander into the kitchen. As I load the dishwasher, 12-year-old Rosa peers at me and pipes up: ‘Your boobs look weird. What have you done?’ I come clean and explain. It doesn’t go well. Elsa, 15, snorts: ‘That’s pathetic!’ I try to explain that the bra simulates ‘real cleavage’ and that I am going to be trying out various looks. ‘Don’t bother,’ she snaps. ‘It makes you look fat.’ Ouch! CONFIDENT AND SEXY WITH  D-CUP . I decide to try my next look on a different audience. Reasoning that my closest friend Nancy is bound to be more supportive, I stuff my bra with the size three and size two inserts — 300cc in total — to give me a much-increased D cup. We’ve booked for lunch at a restaurant, but the problems start before I leave the house. What should I wear? I try on a succession of tunic tops and soft blouses. With a B-cup they look pretty and feminine, but now they are too short and the fabric hangs down from the shelf created by my new boobs. To my horror, I look decidedly fat. Annabel is seen here wearing the inserts that increase her bust size to 34D, although initially self-conscious of her significant cleavage, she was startled by how natural it made her boobs look . I resort to a clinging V-neck dress — a once-worn look-at-me frock bought for a wedding. It’s not what I’d normally wear, but I’m not dressing for myself now; I am dressing for my cleavage — and it’s certainly eye-catching. Nancy is terribly complimentary and I feel rather bouyed up, but as we sit down I feel the disapproving gaze of a couple of mums I recognise, who are lunching near by. Do I look desperate? At 43, am I too old to show off my cleavage? I feel self-conscious, but I press on. My husband and I have tickets to a West End show in the evening, so to ensure maximum impact I invest in an expensive low-cut dress on the basis that if I have ‘it’ (even temporarily) I might as well flaunt it. I am startled to see a new me in the mirror. The boobs look natural, not the typical half-moon shape that screams ‘boob job’, and I feel confident and sexier than usual. It works. My husband, not usually known for his ability to notice a new haircut, outfit or even one of his own children at a distance, cottons on instantly and compliments me in his own special way. ‘You have a figure at last! Does it go bigger?’ GETTING BACKACHE WITH DOUBLE Ds . Next, I try out the boob-job bra at the supermarket — and for this one, I decide to go all-in. With some trepidation I insert size four, size three and size two — 600cc in total. Instantly, I am three cup sizes bigger than I’ve ever been. My posture changes at once: I am pulled forward by the extra weight, leaving me hunched over and exposing a vast swathe of cleavage to my fellow shoppers. Pushing the trolley is even harder work than usual, and I now understand why women with large breasts complain of backache. My bust is enormous and looks wildly out of proportion with my 5ft 4in, size 8 frame. Even walking at a stately pace, my chest jiggles alarmingly. I bend down to pick a box of cereal off the bottom shelf and worry that I’m about to suffer a wardrobe malfunction. Finally, Annabel tested out the 600cc inserts that increased her bust size to a 34E cup. Annabel says she felt her bust became wildly out of proportion to her body as she is only 5ft 4in and a size 8 . I can’t ever imagine running for a bus with a bust like this. Things are no easier at home. I crouch down to sweep the floor and my chest hits my knees; I sit down for a snack and my bust slams on the table before the plate. And sleeping? As I lie down, my boobs separate and sag to the sides alarmingly. I toss and turn but can’t get comfortable. I usually sleep on my side, but then my chest feels squashed. It’s even worse on my front. I try to snuggle up to my husband but once again my DDs are in the way, though to judge by his reaction he doesn’t mind too much. Finally, I remove two of the inserts and drop off flat on my back. The next day, I slip back into my normal 34B bra with great relief. While I’ll be bringing out the D cup on a special occasion — my husband’s birthday, for example — the stop-the-traffic cleavage is far too much for me.
