But it is very cut dependent because they tend to do more fitted looks (big generalization I realize). </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058919 Sun, 08 Sep 2019 00:35:35 +0000 christy 2058919@https://youlookfab.com/welookfab/ <p>In my experience, Theory tends to run small for me but consistently so. I’m always a size or two up in Theory than my usual sizes. </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058914 Sun, 08 Sep 2019 00:16:26 +0000 Anonymous 2058914@https://youlookfab.com/welookfab/ <p>Sigh. I feel huge just reading this. &nbsp;I've always wanted to try Theory . </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058899 Sat, 07 Sep 2019 23:05:04 +0000 Style Fan 2058899@https://youlookfab.com/welookfab/ <p>This is why I don't shop online.&nbsp; I haven't tried on Theory recently.&nbsp; I have a Theory coat which is slightly big on me in the shoulders but the size down was tight in the hips.&nbsp; I loved the colour and was determined to buy the coat.&nbsp; Pre YLF days. </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058862 Sat, 07 Sep 2019 19:29:27 +0000 Kathie 2058862@https://youlookfab.com/welookfab/ <p>I bought a Theory suit 4.5 years ago, and found that it ran TTS, and slightly narrow for me, so exactly as Angie indicated. My jacket is a 6 (and I’m typically a US 4 or 6 in tops, and the pencil skirt is an 8 (I’m more often a 6 in skirts, and 8 in trousers), so the sizing was pretty much what I expected. I do need to have the waist of the skirt taken in a smidge. That said, I haven’t tried on Theory recently. </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058841 Sat, 07 Sep 2019 17:21:53 +0000 Echo 2058841@https://youlookfab.com/welookfab/ <p>I have found Theory to run TTS, but narrow in the shoulders for me. But I remember years ago going into a Banana Republic to try a pair of shorts. I went three sizes down and finally gave up. I knew full well I was not the size I was trying on! That must have been around the time sizing started changing. </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058819 Sat, 07 Sep 2019 15:44:41 +0000 anchie 2058819@https://youlookfab.com/welookfab/ <p>Angie - yes, it could be many factors. I don’t have a lot of experience with US sizing, mostly Banana Republic. I do wear 4 in Banana Republic which is kind of ridiculous because I am just average size and I wonder what all those smaller women wear. Would you say that I would need the same size in Theory as in BR? But 14 years is not that long for such a big change in the sizing. </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058818 Sat, 07 Sep 2019 15:35:21 +0000 anchie 2058818@https://youlookfab.com/welookfab/ <p>Bijou - I haven’t tried NetaPorter, good idea. I did have a look at yoox but they are always risky to order from - no measurements and no reviews at all. </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058816 Sat, 07 Sep 2019 15:32:43 +0000 Angie 2058816@https://youlookfab.com/welookfab/ <p>I few things at play here: </p> <p>I've been wearing Theory for ten years. Personally, I have found them to run consistently TTS. I always wear the same size and my regular size in Theory. I need a narrow fit, and Theory tends to run narrower COMPARATIVELY. Generally, clients who do not need a narrow fit find that Theory runs a little small. They size up.</p> <p>TODAY, sizes are much bigger than they used to be. Footwear is much wider than it used to be too.&nbsp;</p> <p>I bought a size US4 dress at the Gap 23 years. It's the <i><u></u></i><u></u>same size<u></u><i><u></u></i> as the US0 and US00's in my wardrobe today. I am exactly the same size. Size specifications have gone down two to three sizes, and clothing is much wider. When they say that Marilyn Monroe wore a size US8 to12 in the '50s, it's comparable to a size US 2 to 6 today.&nbsp; </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058814 Sat, 07 Sep 2019 15:31:10 +0000 Bijou 2058814@https://youlookfab.com/welookfab/ <p>Anchie - I have never tried Theory - but your experience makes me very wary to try, especially as the only way I can get a Theory suit is online and agree trying three different sizes is crazy. Is the suit you liked on NetaPorter? Net a Porter is very good at providing accurate measurements for each garment. I have never had fit issues with their clothing because I don't base my purchases on the size on the label but rather the actual garment measurements. </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058796 Sat, 07 Sep 2019 15:10:17 +0000 anchie 2058796@https://youlookfab.com/welookfab/ <p>Dana - I am kicking my self for not trying something else just to compare sizing. It could be that only this suit had such inconsistent sizing, but that was the only one i liked.</p> <p>nuancedream - Funny thing is, on the store tag size 8 was translated into XXL and 6 to XL and they kind of felt like that </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058791 Sat, 07 Sep 2019 15:01:35 +0000 nuancedream 2058791@https://youlookfab.com/welookfab/ <p>Theory's pant sizing can run a wee bit on the small side, depending on the pant style, IMO.&nbsp; Their jackets and shirts run TTS for me. I'm a US 4.&nbsp; Women's clothing sizing, regardless of the brand, is insane and makes shopping such a frustrating experience.&nbsp; Maybe the problem isn't vanity sizing, it's insanity sizing! </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058789 Sat, 07 Sep 2019 14:57:44 +0000 Dana 2058789@https://youlookfab.com/welookfab/ <p>It could also be that suit runs large. Did you try on other Theory pieces? It still floors me that a brand can't run consistently, lol!&nbsp; </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058785 Sat, 07 Sep 2019 14:55:13 +0000 Dana 2058785@https://youlookfab.com/welookfab/ <p>Anchie, I think Theory has gotten a little smaller. I have a blazer (unlined linen) that's an 8, a pair of skinny kick flares size 6 and a pair of trousers , size 8. For the most part I'm a 6 in pants. I believe I've had the pants taken in.&nbsp;</p> <p>I had a pair of Theory black pants forever, too!&nbsp; </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058779 Sat, 07 Sep 2019 14:52:52 +0000 anchie 2058779@https://youlookfab.com/welookfab/ <p>kkards - hm.. I don’t think I can fit in UK 8 but if they always run very big and my old suit had UK sizing that could explain but I am not really convinced</p> <p>Brooklyn and Susie - exactly, judging by my old suit I thought that they run small. I am really confused and hesitant to order now. I don’t want to order 3 different sizes - it is a lot of money for me, and refunds take more than a month. And I need it fairly soon, so no time for many order and return cycles:( </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058775 Sat, 07 Sep 2019 14:42:18 +0000 Susie 2058775@https://youlookfab.com/welookfab/ <p>Theory runs small for me. </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058770 Sat, 07 Sep 2019 14:31:26 +0000 Brooklyn 2058770@https://youlookfab.com/welookfab/ <p>Interesting. I’m a size larger in Theory than I am in most brands, so I would have said the opposite - they run small. I don’t get it! </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058732 Sat, 07 Sep 2019 12:14:04 +0000 kkards 2058732@https://youlookfab.com/welookfab/ <p>hmmmm...i haven't noticed this with Theory, but its been a couple of years since i've tried a new blazer from them...wondering if it was sized in "American" vs "British"... for example i'm a US 0 or 2 in a blazer, which translate to "British" 4 or 6 (using Boden as my base) . </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058715 Sat, 07 Sep 2019 11:10:12 +0000 anchie 2058715@https://youlookfab.com/welookfab/ <p>bj1111 - I didn’t notice vanity sizing that much in euro brands that I usually wear. And I didn’t expect this from Theory. And 3 sizes difference - isn’t it a bit too much even for vanity sizing? </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058709 Sat, 07 Sep 2019 10:39:06 +0000 bj1111 2058709@https://youlookfab.com/welookfab/ <p>Vanity sizing. I know I’m fatter but somehow the number on my clothes don’t change.</p> <p>High street brands are notorious for this. Designer brands less so. </p> https://youlookfab.com/welookfab/topic/theory-sizing-1#post-2058703 Sat, 07 Sep 2019 09:35:43 +0000 anchie 2058703@https://youlookfab.com/welookfab/ <p>When I started my current job 14 years ago I treated my self to black Theory pantsuit. Blazer was size 8 and pants were size 10. I loved and wore the suit so much. Eventually elbows got shiny and hems frayed and I had to let it go. I now want to get another Theory suit for fall and went to a store to try it on. I am currently exactly the same size I was 14 years ago. So I reached for the suit in size 8. Oh boy it was huge. I tried 6, it was better but still too big. They didn’t have anything smaller for me to try, so I just assume I need size 4. But I am in shock. Is it possible that sizes have changed so much over the last decade?<br /> How do you find Theory sizing? Does it run true to size for you? How it is compared for example with Banana Republic? I am thinking of ordering online but want to get the size right.</p> <p>I tried also Max Mara and I still needed an 8 - so it is not me </p>
